Valve unveils Steam Link, final Steam controller, Source 2.

I’m happy to see SteamOS is still moving forward. I still think it would be a smart move for Valve to release Half Life 3 as a Linux exclusive. People would definitely buy a Steam Machine just for that, solving the “why would anyone use SteamOS?” problem. If they aren’t considering taking that route, SteamOS doesn’t make nearly as much sense.
