Those wanting to try out Steam’s new linux-based operating system can do so very soon...
While only a select few will have access to the Steam Machine prototypes being sent out to people, along with their interesting new controllers, the Steam OS is available to anyone. Use it on your main PC, use it on an older PC, use it on a media box connected to your TV through Big Picture mode… Or stream games from a PC to a smaller box in some unholy, black magic form of in-home cloud gaming. It’s up to you.
Obviously, being linux-based, you’ll only be able to play games that have been coded for that variety of OS, which is something Valve has made a priority over the last couple years, and others have done for a while. I can’t think of a more important player than Valve to support linux gaming if it’s ever going to catch on. With the shambles that Games For Windows Live was, games becoming easier to develop for multiple OS environments, and Steam less and less beholden to Microsoft, who knows what the future holds.
Check out the Steam OS site for more info, and presumably, when the time comes, a download link.
