Would you want/need/trust a "computer" controlling your entertainment devices?

I think the situation would be ideal. If everything were connected together, there would be a good chance that someone would develop a sort of "Entertainment Operating System" that was specifically for integrating all your devices together.

It'd be neat to sit on my couch and watch tv, and be able to open up a browser window with PiP and see relevant information to what I was watching - a news story or something. Perhaps download a copy of the TV show I just watched half of and switch to the PS3 and play a game. All this while listening to a music collection with auto-generated play lists until I get bored with it and stream Pandora through the stereo and change the PiP browser to the main screen to search for more music that I might like.

I don't think this could come fast enough, but then again I also don't think any one company will do a decent job of it.
