I've managed to erase all my apps on iTunes by accident. I re-installed my machine, fresh copy of iTunes with my podcasts set up, plug in, sync.
In that bar up the top "Erasing application xyz...". All my apps, gone, because i didn't re-auth the computer first. Problem is i can't find any form of "Download all my apps from my account again" option. I think i'm going to have to go through my iTunes purchase history, then try to find all my apps individually!
My biggest problem with iTunes is how laggy it's UI is on Windows. Click on it, does nothing, click again and it responds. Did it do nothing because i was selecting the iTunes window from another one, then clicking again on the actual iTunes UI button? Or, if it does work first time, i've double clicked and it's launched another window! Argh!
How about multi-tasking? I'm afraid to do anything else with iTunes if it's syncing, it'll lag / crash / i don't know what but i have to kill it. It's been syncing, i've clicked to browse podcasts, whole thing freezes.
Final gripe, when using an iPod / iPhone you get a drop-down of Photos, Music, Podcasts below the iPod item on the left hand menu. If i select these i get a list of the stuff on my iPod, great. If i click on the iPod link itself i also get the same items as tabs on the top of the main view. Named the same, appear in the same order and seem like they should be the same items, but yet they have different functionality. Why?!
I'd also say Apple has no idea how a File or Right-click menu works. Why do they have both "Authorise" and "Deauthorise" on the same menu? Can a machine be in some unknown middle ground?
I've had an iPod Touch for quite a while, i really do love it and it made me want the iPhone. However, working with iTunes has made me realise i don't want an iPhone, it's going to be such a horrible thing to manage and it's so locked down. I might have a look at the HTC Hero instead now.
