By then, I sadly expect all computer monitors must be placed such that the users will be facing Mecca :sealed: sitting on their knees on a red carpet.
Nah.... just kidding :-).
I'm about to move to a new house. I plan to have like two LCD monitors mounted to the wall, each with a EeeBox style computer piggy-back-mounted on them. Like that, silent computing would be available in the living. While those EeeBoxes are not the most powerful machines, choosing the correct file format for multimedia content these little boxes could easily double as media playing devices. So no more stacks of devices like it is now. Not a separate machine for radio, video, music, web-browsing, game-playing and so on.
Of course, the central wireless router of the house would be nicely put away into a cabinet, not visible to everyone and it would have some mass-storage device of a couple of TBs to store all the music, movies and documents.
What I also hope (but don't see happening) is virtual intelligence with the devices. It would be fun to have the computer shouting back when it is shouted at :-).
