I'm a new AppleMac convert. Have Ipad, Iphone 4S & MBA. I am not sure how to use the iCloud service. Do I get 5 GB of storage free per device or just per Apple ID ? Stuff on one device is not necessarily required on another device. e.g backup for Iphone 4S is required but the iCloud backup for MBA is also needed but it not the same stuff ( MBA is for work - iPhone is private ) I use Google for mail/calendar/contacts so Apple iCloud is not needed for those . So, do I need to make 3 Apple iCloud accounts for each device ?? email@example.com myipad2@ mymba@ etc ?
