With things like iCloud and Spotify becoming readily available, what are the advantages and disadvantages of keeping your music and other devices not locally available? I would assume one disadvantage would be no access without wi-fi, while an advantage would be saving HD/SSD room. What else is there? Do yoiu think people will even be able to keep their music locally (on a drive) or will they have to stream/do whatever Cloud does with it? Do you think that movies will ever be available in this fashion?
