Comscore has released some numbers for the 3 months from end of October 2010 to end January 2011 and it does not read as good news for Windows Phone 7.  In short, in the US over the period, more Windows Mobile users went Android or other mobile operating systems than converted to Windows Phone 7.

With 65.8 million subscribers now using smartphones in USA, the number of Microsoft mobile OS user shrank from 5.92 million to 5.26 million. So far Microsoft is failing to convert current Windows Mobile users to Windows Phone 7 or winning over new users at a high enough rate to replace them.

Of course as can be seen from the table above, Microsoft is not the only one in the boat, with RIM losing a massive 5% of market share in only 3 months, and Apple barely hanging on its market share, with a 0.1% gain.

The Windows Phone 7 situation is however not static, with an ever increasing Marketplace and imminent arrival on CDMA carriers who form half of the US market.

It is however clear that Microsoft needs to do a lot more, and with a new advertising campaign may already be taking on the challenge.
