Background: 2 iPhones (wife and I), 1 iPad, 1 MacBook Pro. I have 3 calendars setup in iCal and the other devices that I want to start sharing over the air. Wife's got a work calendar, I've got a work calendar and we've got a "home" calendar. Do I really need to buy the family pack of Mobile Me or can I use the single user pack just the same? She does not need any of the other features except to be able to share a calendar and have her calendar info "pushed" to mine and vise versa. So no email, storage, etc.....just to be able to share and edit all 3 calendars on all my devices. Help please!! Thanks!!
