I looked at the video, I looked at your site, and I still don't understand what the big difference between you and Dropbox is.<p>I realize the "Dropbox Killer" title wasn't accurate (or posted by you!), but from your other comments, it does look like you're competing with Dropbox (correct me if I'm wrong). Which is why I keep trying to understand what you do better, and failing.<p>Some background about me: I don't use Google Docs at all (which might be a problem, since your demo seems focused on that). I use and love Dropbox, I'm a paying customer (50Gb). I don't have any major complaints about Dropbox, it's been a dream so far, but I'm always open to alternatives.
