We are also in the same boat. I sure wish I understood it better. I know of quite a few other families who also share an apple id as a family and ARE NOT tech savvy to say the least, so I gotta think Apple has a solution for this seemingly common scenario.
Since the new itunes TOA only allows you to change apple ids per device once every
90 days and iMessage allows you to specify a different email (versus requiring you to use your apple id) I am hoping it is setup like facetime, whereas all devices are logged in with that one apple id but each device has their own iCloud account (.me). Or something like to that effect.
Perhaps some Apple inquiry/feedback is in order.
I'm starting to agree. If you look in Settings under "store" only Music, Apps, & Books are listed. Directly below them, is the Apple ID we all share.
As such, I'm hopeful the other 6 apps (remember, there were 9 iCloud apps) are tied to the @me.com email address. This would make the most sense and would allow individuals to sync only their devices (iPhone to iPad, etc.).
Since the only "purchased" content is really from Music, Apps, & Books it makes since to use the same Apple ID. The only issues with the current implementation is:
1. Can't remove useless, unwanted content from the cue (think of all those junk free apps you've downloaded and subsequently deleted).
2. Can't prevent your children's iDevice from viewing all purchased content. I've check the parental controls, and it will prevent them from installing questionable content, but it will not remove it from their cue.
3. For the hundreds of songs purchased by those in the family with different music tastes, it makes searching for content more tedious on the iDevice because everything is in the cue. We really need a way to remove content from the cue.
If the (@me.com) email address allows individual device synchronization, for the remaining non-media content this will be a good implementation.
Only time will tell.
