Why this new version of iTunes doesn't have Album Art or It didn't show up?

Question

Why this new version of iTunes doesn't have Album Art or It didn't show up?
Also, in my iPod Touch 4th, it erase all album art from my iPod, then i tried to put again a new Album Art, ...download again from the image sites and still ...it didn't show up.? What a waste!
I waste all my time to set all album art on my iPod, then it just gone. kindly pls fix this issue. hate this new version of iTunes, so complicated.
The first thing i saw after i install new version of iTunes, it showed only music files. I don't know where to look for the old version of Sidebar. I keep on trying to look for it where I can see or any sign off button just to show up this stupid SideBar. Also, why i couldn't find? The "Menu Bar" is also hide!
Until i found out in "View" tab. Then i saw the Show Sidebar. Question? why do you need to hide that Side Bar? For what?. it is so so so complicated specially to those people who can't relate for this. (Also the button (from previous iTunes) to show the Album Art, now it's gone. I check every Tab, but there's no way to see the Album Art.)
Another comment. I download also some of my songs to my iPod, I wasted my time to collect all of my favorite music files. Also some are came from CD's and friends. I had all that favorite music in my iPod. Then the version iOS 5.+ came then I updated my iPod, another options to save files (iCloud) but I think there are something that I MISS about updating my iPod. Then suddenly I checked my iPod... all music (with Album Arts) are gone. All Apps are Gone. Videos as well.
If you don't know how to use that iCloud (with only 5GB storage), you'll gonna miss/lost everything.
Then I start all over again, i still have my BACK UP, good to have that. Now it's all set until I update the latest iOS 6. And another version of iTunes.
Then I realized my computer getting slow. I uninstalled it. My laptop started to work fast again. Then I download again the iTunes. So now I know, it has the ability to slow my computer. Everytime I turn on my iTunes, it hang. (Not Responding). Solution... CTRL+ALT+DELETE. Then every second time to open the iTunes, and it works. (it means, to open iTunes, need twice)
Then suddenly my laptop is not working. All my files has been corrupted. My Hard drive doesn't work properly. Now I don't have any stupid BACK UPs. My music files usage is 18 GB, only contacts, documents, notes, or some other files that can only fit to your "iCloud" not my 18GB music files and other photos. Your solution is to BUY more storage. Another COST! Another wasting time to set everything then need to pay more?
If you let your unit (iPod,iPhone,iPad) to export music to PC, or any mini SDcard to use as storage, it won't happen.
There is another....
It has Bluetooth, right?
Use less! Doesn't work. There's no way to use it.
All I need is to install an application to use your bluetooth. (for same unit or Apple unit only). And pictures only can send via Bluetooth if you an application.
Even if you go to "Photos" check if there's a way to send pictures? there is no way to send via Bluetooth, even Photos, Songs.etc. It can't even share some other friends (even they have own iPad, iPod, iPhone or same products) who has a unit with Bluetooth.
And the last.. only one port. there's no way to watch videos through HDMI. No HDMI port, no SD or any card slot. Must to buy their products.
Very costly!
I know (like iPod) it's very friendly to use it, but you  must spend more money first before it can use.

Answer 1

Yes, the old album art view is gone, bu you can see the album art for a song that's playing by clicking on the art image and it will open a bigger view.
Everything else in your post is a waste. I'm not going to spend time reading it. If - and I repeat if, you have a question on how to get the best out of the new look iTunes, post it. But don't spend your time in long rambling negative rants.
