I have no doubt in the future everything will come with a wireless connection. As for moving to the 'cloud' I've really lost interest in it's potential. Onlive are going to charge $15 a month subsription just to play demos or watch trailers, you have to digitally purchase a game if you want to play it. Storage is dirt cheap and I find it more convenient to copy movies/music straight across to my mobile rather than fiddling around with uploads and downloads.
Google seems convinced the cloud is the future. Do you think Google is just pushing their business model?
