Well, I've heard a lot about iCloud and it does sound very useful but I have a question about how it works. Is it more like Time Machine or like iTunes, allowing you to sync only certain things from certain apps (ical, address book, so on) to the iPod. My main concern is, surely Pages will have support for iCloud but, how will apps like Microsoft Word work with it? Can I choose to back up certain folders on my computer? Or is iCloud locked to specific applications? iWork, Mail, iCal, iTunes, iPhoto, Address Book, so forth. Thanks.
