re: Valve Announces its Own Operating System: SteamOS

guys on teksyndicate were speculating that this would basically put the onus on the dells and alienwares of the world to create their steambox for them. At the moment I like the move, although I am not sure how much use I will get out of it. I already have my main PC lined into my TV. Love the family sharing and streaming option though. Will be interesting to see if it will stream 1080 without too much delay. Also, could one stream non steam games (origin and uplay) to the steamOS PC?

TLDR like the idea, but want to see more about the implementation first.
