Valve announces free Linux-based SteamOS

Valve wants to bring the gaming experience straight into your living room with its new SteamOS. The free Linux-based operating system will let you play games from your PC right into your television, turning any computer you own into a Steam-powered console. Games can be streamed right from your PCs or Macs to the Steam-powered machine over your home network. What’s more, SteamOS allows for multiple accounts, letting you share the gaming experience with the people in your household.  

This OS announce is one of three major announcements from Valve, each being represented by a different symbol on Steam’s site. It raises speculation that an actual console or "Steambox" might make its debut.
