Ok guys....plan on purchasing 2 32gig iP4's in the next two weeks and figured I would try out MM for a year and see if I like it. Not too sure if I can get away with 1 single account or the family pack. Let me know if I am understanding this right... If i get a single user account: 1. I will be able to see both phones on the find my iphone app? 2. I will be able to sync 1 single calender and address book across 1 MBP and both iP4's? Hypothetically lets say I add an event onto the calender on my iP4, the next time I sync my iP4 with my MBP the updated calender will be updated with the new event on both devices. Now lets say my wife comes home at a later point and syncs her iP4 with the MBP, but she has added a new event to the calender on her phone. Will calender on her iP4 update with the changes I made earlier and will the MBP calender be updated with her changes? I am assuming the same will go with any Address Book changes under the same scenario? If this is all true, then what advantages am I missing out on by not purchasing the family pack?
