Microsoft boss Steve Ballmer can talk a good game, and Windows Phone 7 looks to be playing hard to claim that prized third spot in the mobile OS pecking order behind iOS and Android.
But the big question, of course, is just how many Windows Phone 7 devices have actually been sold? Into that murky mire has strode the intrepid Eldar Murtazin, and he has a figure for us: 674,000.
Well, that's how many WP7 devices he reckons had found their way into consumers' hands by the end of 2010, which considering when the platform actually launched can be taken as a Q4 sales figure.
So far Microsoft has largely kept quiet thus far regarding WinPho 7 sales, and with reasonable justification too. It simply licences the OS to phone manufacturers, so can justifiably claim that it actually doesn't know how many actual phones have been sold, even if the truth is no doubt a little different.
Ballmer has been willing to share licence sales figures, and his figure by the end of 2010 was sitting at around 1.5 million. So to have turned just under half of those licences into actual end product sales? That actually sounds about right to us, even if Murtazin (as usual) isn't sharing where his info has come from.
