As of January 2008, statistics provided by Net Applications point out that Vista accounts for 10.48% of the market, a climb of over a point in comparison to November 2007, when the operating system had just 9.19%. At the end of October 2007, Microsoft made available the last statistics for Vista sales, claiming to have pushed to its channel partners worldwide over 88 million copies of the platform. At that time, Net Applications estimated a market share of just 7.38% for Vista. The correlation between that percentage and the volume of Vista copies Microsoft has sold is now an indication that the company has passed the 100 million shipped licenses milestone.
2007 proved less favorable for Mac OS X and Linux. Although the two rival operating systems also delivered positive results, with a consistent growth in the background, neither proved a Vista killer, let alone a Windows killer. At the debut of January 2008, Mac OS X owned 7.31% of the market, with Linux at just 0.63%. But, with over 100 million copies shipping in a single year since its introduction, Vista has left its competitors in the dust.
In this context, the uptake of Vista this past year indicates that despite the mixed reviews associated with the platform, the vast majority of XP users are still choosing a Windows iteration rather than switching to Mac OS X or Linux. This perspective is supported by the drop in XP's install base, just 76.91% at the end of December 2007, compared to 84.33% in January 2007.Microsoft, Windows Vista, Windows XP, Mac OS X, Linux, Operating System, Facts and Figures
