Disagree. As we continue to travel up (down ?) the layers of abstraction from actual files in a filesystem to "pipes between dropbox and box.net[1]" it will be more and more difficult to maintain any bearing on what is yours, where it's at, and how to use it. Fast forward a few years from now when half of these players no longer exist, the other half have either been absorbed ("Dell Home Storage, powered by DropBox!") or have "pivoted" because they never made money in the first place (you know damned well that someone inside of dropbox is scheming up some "social" integration on a whiteboard). The consumer, who circa 2012 has been deemed too stupid to even understand a folder, will lose. [1] Whatever that means ...
