I'm looking forward to an API that lets third parties add files to your Cloud Drive. Buy music, get it in your Cloud Drive. Buy a netbook, get the restore CD image in your Cloud Drive. Buy a DVD, get it in your Cloud Drive, etc. Amazon seems to be thinking about this in terms of "when you buy music from your phone it ends up in Cloud Drive", but what I want is for every bit of data I ever pay for to end up here. Because upload speeds are super-slow: it would take hours for me to upload that restore CD. But downloads are fast. So do the uploads Somewhere Else once, and let everyone else download it from their Cloud Drive.
