So... Valve just announced their SteamOS operating system (linux based). Like alot of annoucements, it doesnt say alot, except to pique your curiousity. Though it seems like they say there will be a download available "soon". Definitely interested in hearing more as they reveal new info over the week (according to interpretations of what Gabe said last week).
Article alludes to some devs having been working with it so far, anyone from the community able to comment?
Next update is for their Steam Machines
Next update is for the Steam Controller
