I have a ton of songs, tv shows and movies on my iPad that I can not sync all. Can I use dropbox to put all of this onto their service, that way when I am traveling and what to watch a movie that I could not store on my iPad I can download it with out syncing to iTunes? Basically if I watch a movie on an airplane and then at the hotel want to watch another movie that I could not sync because of storage, log into dropbox, put the movie I just watched into dropbox and then take a movie from dropbox and put it onto iPad.
