It's all in the namenclature
The problem I see is that Apple calls them (iTunes IDs and MobileMe/iCloud IDs) "Apple ID." So, when setting up my phone after the IOS 5 update, I got very confused whenever I was asked for my Apple ID, which turned out to be different for my iTunes Sharing/iTunes store, etc. and my other iPhone functions, like syncing, which use the other (@me.com) one. This is nothing new- it's been this way since the beginning of MobileMe. They've certainly had plenty of time to either come up with 2 ID names or merge them into 1! Let's hope Apple will finally do one or the other!
