The latest quarterly smartphone report from research firm IDC may be cause for celebration in Redmond Washington, home to Microsoft. Their Windows Phone operating system has been trailing both iOS and Android since it was released. IDC’s report says that the Windows Phone operating system grew 150% last quarter.

While for most that would be a cause for celebration, Business Insider reports that what the numbers really reported was that Windows Phone sold 9.5 million smart phones last quarter. That’s out of 261.1 million phones sold overall. So when you break the numbers down, Microsoft had 3.6% of the market. That’s a quick gut check dose of reality.

To add to that news, Apple sold 33.8 million phones during the same period and grew 26%.

As many websites have already reported, Android was the big winner of last quarters IDC report. The Google owned operating system accounted for 80% of the market share last quarter.

As to Windows Phone, IDC said in a press release: “Windows Phone  posted the largest year-over-year growth worldwide of any of the leading operating systems, a result primarily driven by the support of Nokia. By itself, Nokia accounted for 93.2% of all the Windows Phone-powered smartphones shipped during the quarter, marking a new milestone in the company’s short history on the Microsoft platform. Participation from other vendors, meanwhile, still seemed a mixed bag with more vendors participating from a year ago, but volumes still far behind Nokia’s own.”

Perhaps Windows will do even better now that Vine is available.
