I like the app; but instead of telling people to throw away their USB drive maybe you could incorporate a sync feature that would allow users to work on their files offline. Sometimes you just dont have internet access. Just a thought.
yup -- i didn't get to mention it, but a big piece of dropbox is that it's a local/"normal" folder that's synced in the background -- you can work on your files offline (that, among other things, drove me nuts about typical online drives) and get local IO speeds (good for photoshop, film, etc.)
