That's the day when the company will start shipping Steam Machines and Steam Controllers to the 300 selected beta participants. The company said, 'SteamOS will be made available when the prototype hardware ships. It will be downloadable by individual users and commercial OEMs. (But unless you're an intrepid Linux hacker already, we're going to recommend that you wait until later in 2014 to try it out.)"
