@AndyC: I agree that a real roaming profile would be rubbish. But it seems to me that is what is being proposed in all but name. Synchronization of settings: i.e. Favorites, Feeds, Application Settings, and remapping the documents to a skydrive folder isn't that far fetched. Do I like the idea? Nope. Not so much for the data corruption issues, as so much as I like local storage. Until Windows 8 comes out, we really have no idea what they really mean by cloud. We could be looking at something similar to Apple's MobileMe in the end.
