As someone who integrated Google Drive as storage using JavaScript when that came out last year, I've been following Dropbox's efforts closely.<p>The keyword there is "JavaScript", i.e. the application talks directly to the storage from the browser, traffic (data) doesn't have to go via the application providers servers. I've talked to a lot of people who prefer the idea of bringing their own storage and virtually all much prefer direct comms with the storage back-end (once it's explained). Privacy is always high up the list of important things for users.<p>Dropbox started on this a bit later than Google, but as a developer I've been very impressed with the direction they are taking at technical level and the way they've listened to what developers have fed back. I'm liking their platform from a dev perspective more and more.<p>I'm rarely positive about anything, it causes me pain. If any part of the above is quoted, I will deny it.
