Apple fans have made much of the fact that the newest figures from Net Applications show that Apple's share of the operating system market has jumped almost 32% in the past year. But they're ignoring a simple fact: Vista's market share during that same time leaped more than 355%. When you add in other Windows versions, Microsoft owns more than 90% of the market.

Net Applications reports that the Mac had 7.94% market share in June, up from 6.03% a year ago. Going from a little more than 6% to just under 8% may be a big gain when measured as a percentage of growth. But when seen in absolute numbers, it's not particularly impressive.

Vista, by way of contrast, showed far more explosive growth. In June, 2007, it had 4.54% market share. In June, 2008, it had reached 16.14% --- more than a 355% gain. Those numbers are substantial not just in percentage terms, but in raw terms as well. Apple would sell the first-born children of most of its employees if it could ever get to a 16% market share.

Net Applications says that in June, all versions of Windows were on 90.89% of computers, down from 93.34% a year ago. Both Windows XP and Windows 2000 market share shrunk, while Vista's skyrocked.

It's true that in the last year, Mac OSX has made some small inroads into the operating system market. But Windows is still on more than 90% of computers. Shaving a point or two here and there won't change Microsoft's domination.
