The year of Linux on the desktop or living room is here. Today Valve software announced SteamOS, a free Linux-based gaming operating system designed for the TV, DIY enthusiast, and the living room. From the announcement page:

As we’ve been working on bringing Steam to the living room, we’ve come to the conclusion that the environment best suited to delivering value to customers is an operating system built around Steam itself. SteamOS combines the rock-solid architecture of Linux with a gaming experience built for the big screen. It will be available soon as a free stand-alone operating system for living room machines.
