Here’s how to enter Valve’s Steam Machine beta

Valve won’t make you dig through hundreds of chocolate bars to find a golden ticket, but you’ll still need a lot of luck to get picked for its hardware beta later this year.

Earlier today, the developer and digital-game distributor talked about Steam Machines, a slate of devices (including Valve’s prototype) made by various manufacturers that will run the company’s SteamOS, a customized Linux-based operating system. Steam Machines and SteamOS are just the first parts of Valve’s three-pronged attack on living room entertainment, with the third and final piece of news coming this Friday at 10 a.m. Pacific.
