What is the definition of "plays" and/or "skips" in iTunes (version 10.5.3)?

Hi all,
I'm trying to "clean out" my iTunes library by deleting songs I never listen to, and maybe organizing playlists of songs I listen to more often than others. I don't know the technical/offical terms, but there is the "toolbar" that shows artist/track/album/length etc., with options to add or remove categories such as plays/skips/genre and so on... My QUESTION is: What is the definition of a "play" or a "skip?" That is, are they tallied according to how many seconds a track is played before skipping (or continuing)? If anyone can answer this, that would be awesome!
PS. Secondary question: if the plays/skips are determined by a specific time limit, is there a way to change that time? For example, if a skip is defined by clicking "next" before the track has reached 0:05 seconds, can I change that number to 0:03 or 0:10?
Thanks so much!

I agree Luciu, I want to see the official docs for this too anyone know where they are?
My understanding is that anytime you press skip *on your ipod* (not in iTunes while playing). This would appear to disadvantage songs with very long slow outros - as you might want to skip these to get to the next song. This would mean songs with long slow or hidden track outros would accrue additional skip counts.
Perhaps Apple could ignore skips that are within 20 or 30 seconds of the ending to avoid that but yeah some docs would be nice to see.
I use smart playlists to create playlists that do not contain any songs that have been skipped in the past 12 months. That suggests a timestamp is logged with each skip also.

What's the deal with notes and screenshots for upgraded app versions?

We uploaded a new version to replace our 1.1 version of an app in the store.
There was some confusion today that still persists:
(1) For a while, the link to our current version app became invalid and we lost like 2/3rds of our normal sales until the link became valid again. Anybody else ever see that happen? Very frustrating.
(2) Right now, there are two app versions inside itunes connect - the current selling one and the upgraded version awaiting review. I know the old one disappears when the new version is approved and goes on sale. But what is confusing is that the new screenshots and notes for the new version are also displaying in the current app version on sale in the store! I went ahead and added an explanatory note to potential downloaders... but is this a bug or something? Or is that the way it has always worked?
How do people here tend to handle the timing of new screenshots and descriptions when you add new features and want to show them off in your update app?
Thanks,
doug

This has been discussed a number of times here already.
The only items cached for an update release are the specific 'update/what's new in this version' notes.
All other changes will be updated immediately (within a few hours).
You have 2 choices:
1. Post the changes with a note (i.e. this is the next version, awaiting apple approval) so users aren't ticked by downloading the latest actual version.
2. As soon as your update is officially released (monitor it) change the text and images.

They play on my iphone and from the itunes library but not from my ipod touch.

If the songs are still on your ipod, make sure autosync is disabled in iTunes on your computer, connect and right click on it in the device list, then choose "transfer purchases" to copy all bought media and apps from your ipod to your computer.
If the songs are not on your computer and got deleted from your ipod as well, you can't get them back, unless you have a backup of your iTunes library as part of your computer backup.

What's the difference between 2nd and 3rd generation

PLEASE HELP! New Apple user and looking to purchase a used 2nd or 3rd generation ipod touch.
what's the difference between 2nd and 3rd generation?
apparently I am told that the 2nd gen does not have the capabilities of listening without headphone? and the 3rd gen does??

Hi maximumslowness - (great name),
The 2nd gen Touch has one internal speaker, so you can listen to it, (both left and right channels) without headphones.
However - it's a small single speaker and it is not very loud. It's not designed for quality listening (neither is the speaker on the 3rd gen as far as I know) and probably will not be adequate if there is a lot of background noise nearby.
One option is to drop the iPod (not literally!) into an iPod Docking station so that the sound can play out through a self-contained mains-powered amplified speaker, which will also charge your iPod. There are many on the market. On the bottom of the iPod is the 30-pin dock connector which can be used to feed the audio to a docking station. Another option is simply to use a cable to connect from the headphone socket to the audio input on any amplifier.
Yet another is to plug in a small fold-up style speakers, such as

or http://www.amazon.co.uk/Generation-Capsule-iPhone-Laptop-Speaker/dp/B002XNO7FQ/r ef=sr_1_6?ie=UTF8&qid=1332326656&sr=8-6
I've no idea how good the sound is, you'll have to judge that for yourself. The links are both to a UK store, but most countries will have a similar option.
I do not recieve any form of payment or compensatiion for the above links.

I going to recommend again, downloading and installing some video helper applications.
1. http://perian.org/ (this will add a number of different file types to the ones QuickTime already plays)
2. http://www.divx.com/en/software/mac (will add more file types to what QuickTime can play)
Either one of these might be necessary to get MPEG Streamclip to export the video. Failing that the only other thing I have found is an obscurve discussion thread on Avid.com:
http://duc.avid.com/archive/index.php/t-277791.html
I've figured out what the problem is on my end. The video came from Avid on a Windows machine and was encoded with Squeeze. I found out that the 2 seconds of black at the top of the video were at a different frame rate than the rest of the video. I chopped off the 2 seconds of black and started at the first frame of video, exported it with Quicktime Pro and was able successfully view the video in ProTools. Apparently Squeeze will let you create a movie file that has different frame rates within the same movie... This fixed my issue that was exactly as you describe, hopefully it might work for you.
Lastly, you could try converting the video clip using HandBrake

What is the difference betwee STRUCTRUE AND INTERNAL TABLE

what is the difference betwee STRUCTRUE AND INTERNAL TABLE

Hi
<b>Internal table </b>
Internal Tables are runtime objects.
A.     The lines of an internal table always have the same structure
B.     You have to define the structure of the internal table at the begining.
C.     Internal tables require special work area for interface
Types:
STANDARD table
Key access to a standard table uses a linear search. This means that the time required for a search is in linear relation to the number of table entries.
You should use index operations to access standard tables.
SORTED table
Defines the table as one that is always saved correctly sorted.
Key access to a sorted table uses a binary key. If the key is not unique, the system takes the entry with the lowest index. The runtime required for key access is logarithmically related to the number of table entries.
HASHED table
Defines the table as one that is managed with an internal hash procedure
You can only access a hashed table using the generic key operations or other generic operations ( SORT, LOOP, and so on). Explicit or implicit index operations (such as LOOP ... FROM oe INSERT itab within a LOOP) are not allowed.
<b> Structure         </b>
    Structure are data dictionary objects.     Tcode -SE11
     No data records exist in the database for a structure. Structures are used for the interface definition between programs or between screens and programs.
Reward points if this helps.

What is the best malwear detection and protection for use on a Mac?

What is the best malwear detection and protection for use on a Mac?

Mac users often ask whether they should install "anti-virus" software. The answer usually given on ASC is "no." The answer is right, but it may give the wrong impression that there is no threat from what are loosely called "viruses." There is a threat, and you need to educate yourself about it.
1. This is a comment on what you should—and should not—do to protect yourself from malicious software ("malware") that circulates on the Internet and gets onto a computer as an unintended consequence of the user's actions. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the computer, or who has been able to log in to it remotely. That threat is in a different category, and there's no easy way to defend against it.
The comment is long because the issue is complex. The key points are in sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user. Internally Apple calls it "XProtect."
The malware recognition database used by XProtect is automatically updated; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
☞ It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
☞ It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
As new versions of OS X are released, it's not clear whether Apple will indefinitely continue to maintain the XProtect database of older versions such as 10.6. The security of obsolete system versions may eventually be degraded. Security updates to the code of obsolete systems will stop being released at some point, and that may leave them open to other kinds of attack besides malware.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
☞ It can easily be disabled or overridden by the user.
☞ A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
☞ An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
Apple has so far failed to revoke the codesigning certificates of some known abusers, thereby diluting the value of Gatekeeper and the Developer ID program. These failures don't involve App Store products, however.
For the reasons given, App Store products, and—to a lesser extent—other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. Sandbox security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is effective against known threats, but not against unknown ones. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. The built-in security features of OS X reduce the risk of malware attack, but they are not, and never will be, complete protection. Malware is foremost a problem of human behavior, and no technological fix alone is going to solve it. Trusting software to protect you will only make you more vulnerable.
The best defense is always going to be your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "Trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and Internet criminals. If you're better informed than they think you are, you'll win. That means, in practice, that you always stay within a safe harbor of computing practices. How do you know when you're leaving the safe harbor? Below are some warning signs of danger.
Software from an untrustworthy source
☞ Software of any kind is distributed via BitTorrent, or Usenet, or on a website that also distributes pirated music or movies.
☞ Software with a corporate brand, such as Adobe Flash Player, doesn't come directly from the developer’s website. Do not trust an alert from any website to update Flash, or your browser, or any other software.
☞ Rogue websites such as Softonic, Soft32, and CNET Download distribute free applications that have been packaged in a superfluous "installer."
☞ The software is advertised by means of spam or intrusive web ads. Any ad, on any site, that includes a direct link to a download should be ignored.
Software that is plainly illegal or does something illegal
☞ High-priced commercial software such as Photoshop is "cracked" or "free."
☞ An application helps you to infringe copyright, for instance by circumventing the copy protection on commercial software, or saving streamed media for reuse without permission. All "YouTube downloaders" are in this category, though not all are necessarily malicious.
Conditional or unsolicited offers from strangers
☞ A telephone caller or a web page tells you that you have a “virus” and offers to help you remove it. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
☞ A web site offers free content such as video or music, but to use it you must install a “codec,” “plug-in,” "player," "downloader," "extractor," or “certificate” that comes from that same site, or an unknown one.
☞ You win a prize in a contest you never entered.
☞ Someone on a message board such as this one is eager to help you, but only if you download an application of his choosing.
☞ A "FREE WI-FI !!!" network advertises itself in a public place such as an airport, but is not provided by the management.
☞ Anything online that you would expect to pay for is "free."
Unexpected events
☞ A file is downloaded automatically when you visit a web page, with no other action on your part. Delete any such file without opening it.
☞ You open what you think is a document and get an alert that it's "an application downloaded from the Internet." Click Cancel and delete the file. Even if you don't get the alert, you should still delete any file that isn't what you expected it to be.
☞ An application does something you don't expect, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
☞ Software is attached to email that you didn't request, even if it comes (or seems to come) from someone you trust.
I don't say that leaving the safe harbor just once will necessarily result in disaster, but making a habit of it will weaken your defenses against malware attack. Any of the above scenarios should, at the very least, make you uncomfortable.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it—not JavaScript—in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the left side of the address bar when visiting a secure site.
Stay within the safe harbor, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself.
7. Never install any commercial "anti-virus" (AV) or "Internet security" products for the Mac, as they are all worse than useless. If you need to be able to detect Windows malware in your files, use one of the free security apps in the Mac App Store—nothing else.
Why shouldn't you use commercial AV products?
☞ To recognize malware, the software depends on a database of known threats, which is always at least a day out of date. This technique is a proven failure, as a major AV software vendor has admitted. Most attacks are "zero-day"—that is, previously unknown. Recognition-based AV does not defend against such attacks, and the enterprise IT industry is coming to the realization that traditional AV software is worthless.
☞ Its design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere. In order to meet that nonexistent threat, commercial AV software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
☞ By modifying the operating system, the software may also create weaknesses that could be exploited by malware attackers.
☞ Most importantly, a false sense of security is dangerous.
8. An AV product from the App Store, such as "ClamXav," has the same drawback as the commercial suites of being always out of date, but it does not inject low-level code into the operating system. That doesn't mean it's entirely harmless. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An AV app is not needed, and cannot be relied upon, for protection against OS X malware. It's useful, if at all, only for detecting Windows malware, and even for that use it's not really effective, because new Windows malware is emerging much faster than OS X malware.
Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else. A malicious attachment in email is usually easy to recognize by the name alone. An actual example:
London Terror Moovie.avi [124 spaces] Checked By Norton Antivirus.exe
You don't need software to tell you that's a Windows trojan. Software may be able to tell you which trojan it is, but who cares? In practice, there's no reason to use recognition software unless an organizational policy requires it. Windows malware is so widespread that you should assume it's in every email attachment until proven otherwise. Nevertheless, ClamXav or a similar product from the App Store may serve a purpose if it satisfies an ill-informed network administrator who says you must run some kind of AV application. It's free and it won't handicap the system.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have all the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user, you don't have to live in fear that your computer may be infected every time you install software, read email, or visit a web page. But neither can you assume that you will always be safe from exploitation, no matter what you do. Navigating the Internet is like walking the streets of a big city. It's as safe or as dangerous as you choose to make it. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

What is the different between component and component type in extract struc

Hi All,
What is the different between component and component type in the Extract Structure?
I used them, but I never really know the different between them yet.
Thanks,
Grace

The difference between Component and Component Type are:
Component This is essentially the field name in the extraction structure. These can either be SAP delivered field names or custom field names (e.g. Y* or Z*).
Component Type This defines the data definition for the field, along with associated attrributes and descriptions for anything using that Component Type, to define the corresponding Component. If you double-click on any Component Type in an extraction structure, it will show you the definitions that have been setup for that Component Type (will display as Data Element but it's essentially synonymous - Component Type refers to structures and Data Elements refer to tables).

Could any one tell me what is the difference between swfloader and module loader?

Hi All,
                      Could any one tell me what is the difference between SWFLoader and Module Loader in Flex3 in detail?

Hi,
ModuleLoader is a kind of strange API that is really just intended to look like SwfLoader for modules that contain a single visual component, and hides most of the module loading infrastructure, which is all about class factories.
What I mean by "only loaded once" is that if you have several places in the code that call the ModuleManager.getModule("url").load() call, it will only ever get loaded over the wire and interpreted once, subsequent "loads" will just re-dispatch pseudo-load events to the new client. In other words, the class factory is a singleton for a given url. Unloading is a totally different story. As you note, not everything is truly unloadable, because there may be lots of references to stuff in
the module that will keep it alive and un-GC'ed.
I suggest playing with the low-level API so that you understand the backing implementation, and this should help you understand the limits of ModuleLoader.
The main difference between modules and applications is that modules have lower overhead, and they only ever get loaded once, no matter how many times you load them. If you're using the ModuleLoader API, keep in mind that you're losing about half the functionality of the module system. I will assume that you are, because otherwise it would be obvious where to expose methods. You might want to play around with the lower level ModuleManager API just to get a hang of what's going on - ModuleLoader is a pretty thin veneer over the lower API.
                Basically, what you want to do is to have your module implement an interface, say IModuleWhatever.
Also try and refer to this link which was previously discussed in this forum..

What are the Relations between Journalizing and IKM?

What is the best method to use in the following scenario:
I have about 20 source tables with large amount of data.
I need to create interfaces that join the source tables into target tables.
The source tables are inserted every few secondes with about hundreds to thousands rows.
There can be a gap of few seconds between the insert of different tables that sould be joined.
The source and target tables are on the same Oracle instance and schema.
I want to understand the role of: 'Journalizing CDC' and 'IKM - Incremental Update' and
how can i use it in my scenario?
In general What are the relations between 'Journalizing' and 'IKM'?
Should i use both of them? Or maybe it is better to deelte and insert to the target tables?
I want to understand what is the role of 'Journalizing CDC'?
Can 'IKM - Incremental Update' work without 'Journalizing'?
Does 'Journalizing' need to have PK on the tables?
What should i do if i can't put PK (there can be multiple identical rows)?
Thanks in advance Yael

Hi Yael,
I will try and answer as many of your points as I can in one post :-)
Journalizing is way of tracking only changed data in your source system, if your source tables had a date_modified you could always use this as a filter when scanning for changes rather than CDC, Log based CDC (Asynchronous in ODI, Logminer/Streams or Goldengate for example) removes the overhead of of placing a trigger on the source table to track changes but be aware that it doesnt fully remove the need to scan the source tables, in answer to you question about Primary keys, Oracle CDC with ODI will create an unconditional log group on the columns that you have defined in ODI as your PK, the PK columns are tracked by the database and presented in a Journal table (J$<source_table_name>) this Journal table is joined back to source table via a journalizing view (JV$<source_table_name>) to get the rest of the row (ie none PK columns) - So be aware that when ODI comes around to get all data in the Journalizing view (ie Inserts, Updates and Deletes) the source database performs a join back to the source table. You can negate this by specifying ALL source table columns in your PK in ODI - This forces all columns into the unconditional log group, the journal table etc. - You will need to tweak the JKM to then change the syntax sent to the database when starting the journal - I have done this in the past, using a flexfield in the datastore to toggle 'Full Column' / 'Primary Key Cols' to go into the JKM set up (there are a few Ebusiness suite tables with no primary key so we had to do this) - The only problem with this approach is that with no PK , you need to make sure you only get the 'last' update and in the right order to apply to your target tables, without so , you might process the update before the insert for example, and be out of sync.
So JKM's provide a mechanism for 'Change data only' to be provided to ODI, if you want to handle deletes in your source table CDC is usefull (otherwise you dont capture the delete with a normal LKM / IKM set up)
IKM Incremental update can be used with or without JKM's, its for integrating data into your target table, typically it will do a NOT EXISTS or a Minus when loading the integration table (I$<target_table_name>) to ensure you only get 'Changed' rows on the load into the target.

how can i use it in my scenario?Hopefully I have explained it above, its the type of thing you really need to play around with, and throroughly review the operator logs to see what is actually going on (I think this is a very good guide to setting it up : http://soainfrastructure.blogspot.ie/2009/02/setting-up-oracle-data-integrator-odi.html)
In general What are the relations between 'Journalizing' and 'IKM'?JKM simply presents (only) changed data to ODI, it removes the need for you to decide 'how' to get the updates and removes the need for costly scans on the source table (full source to target table comparisons, scanning for updates based on last update date etc)
Should i use both of them? Or maybe it is better to deelte and insert to the target tables?Delete and insert into target is fine , but ask yourself how do you identify which rows to process, inserts and updates are generally OK , to spot a delete you need to compare the table in full, target table minus source table = deleted rows , do you want to copy the whole source table every time to perform this ? Are they in the same database ?
I want to understand what is the role of 'Journalizing CDC'?Its the ODI mechanism for configuring, starting, stopping the change data capture process in the source systems , there are different KM's for seperate technologies and a few to choose for Oracle (Triggers (Synchronous), Streams / Logminer (Asynchronous), Goldengate etc)
Can 'IKM - Incremental Update' work without 'Journalizing'?Yes of course, Without CDC your process would look something like :
Source target ----< LKM >---- Collection table (C$) ----<IKM>---- Integration table (I$) -----< IKM >---- Target table
With CDC your process looks like :
Source Journal (J$ table with JV$ view) ----< LKM >---- Collection table (C$) ----<IKM>---- Integration table (I$) -----< IKM >---- Target table
as you can see its the same process after the source table (there is an option in the interface to enable the J$ source , the IKM step changes with CDC as you can use 'Synchronise Journal Deletes'
Does 'Journalizing' need to have PK on the tables?Yes - at least a logical PK in the datastore, see my reply at the top for reasons why (Log Groups, joining back the J$ table to the source table etc)
What should i do if i can't put PK (there can be multiple identical rows)? Either talk to the source system people about adding one, or be prepared to change the JKM (and maybe LKM, IKM's) , you can try putting all columns in the PK in ODI. Ask yourself this , if you have 10 identical rows in your source and target tables, and one row gets updated - how can you identify which row in the target table to update ?

Thanks in advance YaelA lot to take in, as I advised I would reccomend you get a little test area set up and also read the Oracle database documentation on CDC as it covers a lot of the theory that ODI is simply implementing.
Hope this helps!

What are the folders 0-9 and a-f in firefox 4.0b cache ?

'''What are the folders 0-9 and a-f in firefox 4.0b cache ? '''

Even worst FF 4 does not store videos and .swf files in cache. When you watch a video or play a game and leave the page and want to see the video or play the game again you must wait for it to download again. It is not saved in any of the cache folders. What is going on with Mozilla and Firefox. Have they bowed down to the big boys with this new browsers.

Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

Looking for new laptop what are the differences between pro and air? Besides size. Does the air preform like the pro?

The NEW macbook Pro and Air are EXTREMELY close in form factor
The newest macbook Pro is essentially a larger macbook Air with Retina display and options for speed in increasing prices up to an independent graphics and quad core processor.
both Air and new Pro now have PCIe SSD and permanent RAM.
The Air is the lightweight portable form factor, fast to boot and shut down, but with longer battery life than any of the macbook pro in 13"
Now the new macbook Pro and macbook Air are extremely close in form factor and nature.
both have 802ac wifi
both have permanent RAM, no superdrive
both are slim profiles and SSD
The only real differences now are (in the most expensive Pros) faster processors and quadcore processors and top end model autonomous graphics.
....and of course the retina display
both are now "very good for travel"
Other than features the form factor of the Air and Pro are VERY close now,....so now its merely a matter of features and price more than anything.
You need an external HD regardless of what you get for backups etc. Drop into an Apple store and handle both and make your choice based on features, such as Retina or non-retina, .... both at a distance now look like the same computer.
The Pro weighs more, ....but nowhere near what it used to just a month ago on the older macbook Pros
The NEW macbook Pro is a different creature entirely than the older macbook Pro, .....the new Pro is thicker than the Air, but id frankly call the NEWEST Pro a "macbook Air with Retina display" , or
Maybe a “macbook Air PRO with Retina display”
Instead of Air VS Pro now,.....its really a smooth transition from Air to pro without comparing say, 2 different creatures, now its like contrasting a horse from a race horse.
Either one in 8gig of RAM (preferably)... the 4gig upgrade costs very little, the I7 you will notice only 15% faster on heavy applications over the I5, and NOTHING on most APPS.....I5 has longer battery life.
As you see below, the non-Retina 13" AIR is 82% of the Macbook with Retina display in resolution
there is no magical number of pixels per inch that automatically equates to Retina quality.

A huge internal SSD isnt a game changer for anything, you need an external HD anyway
what you WONT READ on Apple.com etc. is that the larger SSD are MUCH FASTER due to SSD density
"The 512GB Samsung SSD found in our 13-inch model offers roughly a 400MB/s increase in write speeds over the 128GB SanDisk/Marvell SSD"
