Andy Ihnatko [writing in MacWorld](http://www.macworld.com/article/160933/2011/07/ihnatko_icloud_macbook_air.html) suggest that iCloud is more than just a replacement for MobileMe.
> It’s so very clear to me now that just as Superman is the living ideal of Truth, Justice, and the American Way, the 11” [MacBook] Air is the tangible ideal of iCloud. You grab it when you leave the office and that’s it. No syncing, no updating, no need to trust that you’ll find WiFi when you get to where you’re going: iCloud kept your iCloudBook’s files up-to-date as you were updating them on your iMac so you’re already good.
