Research released today indicates that in North America, Apple's Mac OS X is gaining traction, while the Windows share of the OS market is shrinking ever so slightly. That's the report from Quantcast, a company that measures and analyzes web traffic. They say that the market share for Mac OS X is up 7% from December to January. Microsoft held steady for the last 3 months of 2009 with the release of Windows 7, but started a slow decline again in January.

According to Quantcast, Apple has a 10.9% North American share as of January, while Windows has 86.8%. An interesting note is that the largest group of users is on Snow Leopard, Mac OS X 10.6, while Windows XP dominates on the Microsoft side. Apple's relative share in North America is up 29.4 % in a year, while Windows share is down 3.8%.

These figures measure web consumption, so if you're not web connected your OS choice doesn't count. Quantcast measures ad supported sites, so huge traffic sites like Google, Facebook, Yahoo and others don't supply statistics.
