Valve promised three big announcements and the first - revealed today - is that it is working on its own Linux-based operating system called SteamOS. Valve said that it came to the conclusion that the best environment for delivering games is one that it has created. While Valve promises that the new OS will be open-ended as Linux-based operating systems usually are, some are concerned that Valve is creating its own version of the "walled garden" that the company complained about with Windows 8.
"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," the SteamOS page states. "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."
Obviously the OS will work well with Steam Big Picture Mode, which makes using Steam games easier on high definition television sets, though Valve has not said if it is working on custom hardware to go along with the OS or if it will rely on third-parties.
Valve promises that you'll still be able to play all of your Mac, Windows, and Linux games from within Steam OS, and that it supports family sharing, various movie and music services (could we see Netflix and Hulu on Steam OS? Maybe), and much more.
