Canalys have some numbers for the US market which shows half a million Windows Phones were shipped in Q4 2011 into the US market. This represents 1.6% of the market.Â It is not clear of Canalys defined Windows Phone strictly as Windows Phone 7, or included Windows Mobile also.
For the full year they claim 2.2 million Windows Phones were shipped , suggesting shipments actually slowed down at the end of the year.
This, as with other recent analyst numbers, indicate Microsoft is still to implement a strategy that will work in competing against iPhone and Android.
Thanks Arun for the tip.
