Well if you want to compete with Google Drive you should probably look into starting an email service with good integration for file sharing. Don't know if you do it already but since I don't really log in to Dropbox daily and I do to Gmail, haven't really looked into it. And the Gmail + Drive combo works pretty well although I heavily dislike the Drive file user interface (why it can't be more like regular file system interface?)

I use Dropbox only because it's easy to edit/add files from the file system (and I don't like Microsoft or Google enough to give their services a chance).
