In November 2009, 69% of all internet users use Windows XP, 18% use Windows Vista and 4% Windows 7. Now in December, Windows 7 finally passed the 5% mark. In comparison, MAC OS X only had a market share of about 2,6% in November 2009 and their share is even dropping slightly.

Actually, it’s not very surprising that Windows Vista has a market share of almost 20%, but what surprised me is the fact that Linux takes only 1% of the market share, I expected it to be a little bit higher with all the linux distributions out there.

We will be looking at the Windows 7 market share in a month again. A lot of people buy a new PC for Christmas or for the new year, so the market share of Windows 7 might increase by another 2-4% in January 2010. The question is, when will Windows 7 surpass the market share of Windows Vista?

Any predictions?
