Windows 7 passes XP on Steam, Mac OS X grabs 8% share
 

Four months ago, Windows 7 passed Windows Vista on Steam, the leader of the digital game distribution market, and we predicted that XP was in its crosshairs. Last month, Windows 7 passed Windows XP, making it the most popular operating system on Steam. Windows 7 is also the first version of Windows where gamers are adopting 64-bit faster than 32-bit. That said, there are still more 32-bit XP users than those on Windows 7 64-bit.
