I can't grasp the concept of iCloud can someone shed some light? I'd like to integrate everything into the Apple system with iCloud but not sure how to set it up, I'm confused. I have Microsoft exchange set up for my contacts and Gmail for my mail. I have a me.com email address. iTunes has always been set up via my Gmail email address. Also all iPhones are hooked to same iTunes email address and would like to start having each device have their own iTunes account(is that best way?).
