Either way, it would be a shame if Google sank Dropbox and I would resent it. Dropbox is a GREAT service for free, then charges if you like more space. They offer the best use cases around for developers who do a lot of cross device work. You can keep all your information on all testing environments, and even share folders with others (or other accounts) and not really face limitations (i.e. no linux support). And with Google already getting strict about storage on Android, you can only suspect a Chess move to gain control with a dollar 99 on the hook.
