Chitika Insights grabs online advertising data to monitor and report on Internet trends, one of which is the market share of various computer operating systems. There was a surprise reported for Mac OS X in the latest report -- the market share for Apple's desktop/laptop OS climbed 1.039% from 9.6% to 10.6% in the month of September.

That may not sound like much, but consider that a sustained increase over a full year would have Mac OS X gaining another 12% of the OS market. Of course, that's unlikely to happen, but it's good to see that the release of Lion propelled OS X adoption by a significant amount in just one month.
