While it must be disappointing news for those internationally that the 300 Steam Machine beta boxes will be confined to the U.S. only, it's not all bad. Friday the 13th will bring some good fortunes to those who want to take the SteamOS software for a spin, as Valve will make it downloadable tomorrow.

"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.)
