Via Rock Paper Shotgun and Primotech, the latest in Valve's ongoing PC hardware survey via the Steam service. Some very interesting stuff in there, though probably nothing too surprising. From RPS's analysis: "Vista has shown a small increase in representation, but clearly nowhere near where Microsoft would have desperately hoped. Previously 7.99% of gamers were using the latest operating system. Now it's 16.91%, with a vast 81.13% sticking with XP. Rather confirming Valve's position on DX10, and what a massive waste of time it is developing for Vista only."
