Note to Box, please make your file formats plain html or something exportable.<p>I think it will take a leap of faith for a company to start creating all their docs on Box, vs Google Docs which has been around longer. I would feel better if I saw them stored in such a way that I wasn't afraid I was stuck with you forever.<p>Maybe you can create the first modern, open docs file format for the web. Maybe that's just html.<p>IE not .gdoc (.bdoc)<p>That is all to say, I'm not sure you can win this war on features or usability (vs Apple and Google) but you might be able to win with security + openness.
If it has real, proper, version control with named checkpoints then I'll check it out. I still struggle to believe that Google Docs doesn't have the ability to create a named version alongside its version-for-every-change tracking.
