One day the idea that you don't have internet access will be just as silly as saying you don't have electricity. Its in the very infant stages but its coming. For what its worth Im typing this on my Cr-48 which has 3G so I'm pretty much there.
I'm inclined to agree especially in cases like movies or music. The idea that we all have a copy of a song on our hard drives is odd. Leaving aside ideas of copyright and licenses there really isnt a reason all media shouldnt live in some kind of shared music/video folder in the sky. I'm going to watch Breaking Bad S2E4 maybe a handful of times and eventually forget about it. Keeping it in the cloud frees the user from needing to think about keeping it or backing it up or deleting it.
Or maybe I'm biased from living in a fairly cloudy world already.
