Today Valve Software announced SteamOS, a Linux-based gaming operating system designed for, as Valve puts it, "living room machines." They say, "In SteamOS, we have achieved significant performance increases in graphics processing, and we're now targeting audio performance and reductions in input latency at the operating system level. Game developers are already taking advantage of these gains as they target SteamOS for their new releases." One major feature they're touting is the ability to use the SteamOS machine to stream video games from other Windows and Mac computers in the house to your TV. They mention media streaming as well, but without much detail. "With SteamOS, 'openness' means that the hardware industry can iterate in the living room at a much faster pace than they've been able to. Content creators can connect directly to their customers. Users can alter or replace any part of the software or hardware they want. Gamers are empowered to join in the creation of the games they love. SteamOS will continue to evolve, but will remain an environment designed to foster these kinds of innovation."
