I had the same thought. While looting mobile for some our better interactions (Swipe gestures for OS X), I don't see how this is more efficient that what we have. Mobile work flows are far more convoluted and time sucking that current desktop models. This seems to introduce unnecessary steps, and is completely touch pad dependent. Tagging exists in modern OSes already, plus there's a strong use case for folders. There's a reason why dropbox is popular on iOS.
