Looks like amazon is now offering cloud storage(5GB) for free!! With what so far seems to be a great (web) user interface. They are advertising it as a great place to store all your music and have it where ever you need it, but from what I have been reading it also accepts other files such as, photos videos and documents. All you need to use the Could Drive is a web browser. There is no software like Dropbox. They do have a cloud player that you can download for you Android Device but its does not look like that have an app for iOS yet(?).
