An anonymous reader writes "Steam is now being used by thousands of gamers running a Linux OS, and Valve has got to the point where they are happy to start urging Windows users to make the switch. Proof of that comes from a 'Join the Beta' promotion on the homepage of Steam suggesting you try Steam for Linux. There's even a download link to get Ubuntu 12.04 LTS, which removes yet another barrier to entry. With Gabe Newell's clear hatred of Windows 8, this shouldn't be a surprising move. We aren't going to see another version of Windows appear for a few years, so in Valve's eyes pushing Linux to gamers makes a lot of sense."
