SteamOS is based on Debian, not Ubuntu, and unless something has changed with Valve's vision, the last thing I read was SteamOS is NOT going to be a standard OS; the Debian desktop exists purely in beta for debugging and testing, and will be removed from the final product. As a result, you can't install other software (which is why I find Gabe's comment about having no issue installing Origin on a Steam Machine very confusing).Or have I missed something?Plus, this article just further illustrates how up-in-the-air the entire concept of a Steam Machine actually is. If they're aimed as "living-room entertainment centres" not "optimised gaming rigs" then why do some of them come with one or even 2 GTX Titans? That's a hardcore gaming rig!And if SteamOS is treated as any other Linux distro so you can install other software and do non-gaming things, they why even bother with all of this when anybody's choice of Linux with the standard Steam client will do the same job (except the game streaming)?
