I have a MacBook Air, MacBook, iPad, and iPhone. I currently use Snow Leopard on the Macs and iOS 5 on the iOS devices. I haven't upgraded to Lion because it looks and feels too iOS-like for a desktop operating system and there are quite a few features and interface elements it removed from Snow Leopard. Since MobileMe expires on June 30th, I'll finally be upgrading my main computer, the MacBook Air, to Lion. The wording on the MobileMe transition page confuses me a bit. I don't plan on using my MacBook much at all, so I don't think I need the syncing capabilities of MobileMe/iCloud on it. If I upgrade my MacBook Air to Lion and officially migrate my MobileMe account to iCloud, can I safely assume the MacBook will work as normal in the future, just without MobileMe/iCloud features? Because the iCloud transition instructions ask you to confirm that all your devices are running Lion and iOS 5, will the fact that I have my MacBook registered as a MobileMe device cause problems if I don't log out of my MobileMe account on the MacBook? Rather than go to the trouble I'd rather just ignore it, assuming that won't cause any problems. Thanks!
