I have the following setup which worked beautifully before iCloud came along:
- a "master server" Mac Mini through which I make all iTunes purchases for the entire family under a single AppleID. The following devices sync with this computer:
- Dad's iPhone
- Dad's iPad
- Mom's iPhone
- Mom's iPad
- a "satelite" iMac for the children to which I copy any apps, movies, and music they want. The following devices sync with this computer:
- Son's iPod Touch
- Daughter's iPod Touch
I want to share:
- App purchases
- Music purchases
- Movie purchases
- Master family contacts/address book
- Family calendars
I need to separate:
- iMessage accounts for each device
- FaceTime accounts for each devices
I resorted to using Google calendars some time ago because Google did a much better job of keeping separate calendars for each family member and controlling who could update what, so I don't attempt to sync calendars through iCloud. I set up each device to use the same AppleID (as they always have) for both iTunes and iCloud. iTunes sharing works great (except that I have to give my wife my password and enter my password for my children whenever they want to make purchases). We just manage the sync settings for each device manually (syncing specific playlists, etc. to each one).
I set up each device to use it's owner's e-mail address for messages by fiddling with the settings for "Messages" in the Settings app. This did a great job of sending messages to the correct device (except that my wife and I own two devices each, so incoming messages may go to both devices, which isn't all bad).
Everything seems to be working great except for one thing. Siri! If I tell Siri who I am, then Siri changes it's behavior on my wife's iPhone and starts calling her by my name. If she tells Siri who she is, then Siri changes it's behavior on my iPhone and starts calling me by her name. Why are Siri settings sync'd between devices!? Is Siri going to be the straw that forces me to maintain separate AppleID's!? Will that force me to start paying double for iTunes purchases? Will it mean that we can no longer share our contacts/address book among the entire family?
