Back in September of 2013, Valve revealed SteamOS - now it's time for action. Here in June of 2015, just a bit under two years later, Valve's revealed the final iteration of the Steam Controller, the key to the system - the one component you can't buy anywhere else. Every other piece of this gaming environment can be had elsewhere, or run on a PC you've got at home. After months and months of preparation, Valve's presented a system they hope will take over your living room. Is it too late? Has the company lost all momentum? Is SteamOS dead in the water before it launches in ernest?
