And what about the "old-timers?" All my itunes and app store purchases are under a mac.com email address as my ID. My Mobile Me sign-ins are associated with a me.com address. (The mac.com domain no longer functions for actual email, and hasn't for years.) It's my understanding that Apple won't even consolidate these two types of accounts!
Hopefully the cloud can be under my me.com login and it will recognize my purchased music as being owned by me by virtue of the fact is resides in iTunes on my computer, and having two different logins won't matter.
Any input?
That is correct. I had my me account for a while and never used it to purchase anything as i had an older account that I always used for purchases. I can stay signed into my old account for the itunes store and then backup those apps into the cloud with my me account.
