It definitely seems to be the direction things are converging, but what you are talking about is much more than file storage, it's a full scale cutting edge multi-platform cloud OS. While it is definitely conceivable, if you look at how far the various single-platform client-based OSes still have to go, it sheds some light on how monumentally complex the task truly is. Especially considering that these OSes have companies many, many times larger and more experienced than dropbox backing them. File storage is certainly a critical piece of the puzzle and I could see them making some major inroads towards standardizing the cloud, but I think the full breadth of your vision is still pretty far off. Fun to speculate on though for sure.
