FRUSTRATION - why can't I add music from multiple computers to my iPhone??

Question

I use multiple Mac computers in my life. My home computer has about 30 gigs of music. My work computer has about half that. Therefore syncing in any case is not an option. I have added some music from home to my new iPhone, and I want to do the same from my work computer but cannot! WHY?? I can do this with my 5th gen Video iPod no problem.
Plugged into my work computer now, I try to set the iPhone again to "manually manage music," but it still tells me the iPhone is synced with another computer (it is not, since I immediately disabled the sync feature before adding music). Is this going to be the case if I want to add photos from multiple computers, etc., too?
WHY?? WHY??? WHY?????
SO FRUSTRATING...

Answer 1

You're welcome.
Maybe I'm missing something, but i still struggle to see the connection. Disk mode is the iPods ability to be mounted as a disk on the desktop, allowing the free disk space to be used manually. It exists completely outside the iPods normal, iTunes-driven functions, right? What we are missing on the iPhone is a simple feature from inside iTunes – a feature that all other iPods (as far as i know) have. Strange that the "Amazing iPod" does not.
Disk mode has everything to do with the ability to transfer iTunes content to an iPod from multiple computers. This is not a simple feature from inside iTunes.
Do you have an iPod? If so, are you transferring iTunes content from more than one computer to your iPod? If so, do you have disk mode enabled for your iPod? If yes, turn off disk mode and test if you are still able to transfer iTunes content from more than one computer to your iPod.
Nothing prevents me from admitting when Apple goes wrong or disappoints, but this is not the place for it. This is a user to user help forum for technical support issues and questions only which has a terms of use. Discussing Apple's policies and procedures and ranting is specifically against Apple's terms of use for these discussions.
Since this is a user to user help forum only, no one here knows Apple's reason or reasons why disk mode is not supported with the iPhone. The only answer you will get here or anywhere else for that matter is someone's opinion, unless Apple makes an announcement or information is provided by an exec during an interview. IMO, there must be a valid reason or reasons why disk mode is not supported with an iPhone since it is supported with iPods. Since disk mode is supported with iPods, more than likely there isn't a technical reason why it isn't supported with an iPhone, so I seriously doubt that Apple decided not to support disk mode with the iPhone just for kicks, or for no valid reason or reasons whatsoever on their part.
Until I know Apple's reason or reasons, it is difficult for me to admit Apple has gone wrong in this regard, for it may make Apple right for a reason or reasons we don't know, which can be disagreed on. Once facts are known, just because you believe Apple has gone wrong and/or you are disappointed doesn't mean I believe the same, which may or may not have anything to do with being an Apple fan - maybe we just don't agree.
My brand loyalty goes only so far. I did plenty of research on the iPhone before making the decision to purchase one. Before purchasing an iPhone, I can count on one hand the number of MMS I had exchanged. I have used a number of Palm handhelds for business - before they began selling a Palm cell phone, and I don't recall editing a word or excel document once during all that time. I wasn't interested in doing so with such a small screen, and since I wasn't interested in doing any editing, cut/copy/paste wasn't critical to me either.
If these features were very important to me - features I used on a daily or very regular basis, I would not have purchased an iPhone regardless the other features it includes. I certainly wouldn't purchase one anyway knowing these things, followed by wasting my time at an Apple user to user help forum for technical support issues and questions whining and ranting about it, which is common here by an immature small percentage of users. There is nothing wrong with providing constructive comments here, which constructive being the key word. There are some folks here who don't know what the word constructive means and don't have a clue about how use it.
