I currently have an iphone 4 and an ipad 2 running IOS 5 and a macbook pro with snow leopard. I would just like to have my mail, contacts, calendars, reminders, bookmarks and notes all syncing together, but from what I am understanding... 1. I HAVE to have Lion running on my macbook pro and 2. more than 5 gigs of storage space. When I tried to turn on iCloud with the 2 devices above (and only the items listed syncing), I quickly ran out of space. Is this correct and is iCloud just for Lion users with only 1 IOS device and selected items to sync like the ones I wanted?
