Microsoft has decided to finally dish out some sales figures for its new Windows Phone 7 platform, but alas, these are not the sales figures we are looking for. Instead of giving us the juicy number of actual devices sold to end users, the Redmond crew has given us a neatly rounded 1.5 million number of sales to mobile operators and retailers. That tells us that the mobile industry is buying into Microsoft's new OS, and it'd be foolish not to, but it doesn't really educate us much on the relative success of the platform's launch. All that Microsoft's Achim Berg would say is that early sales have been "in line" with his company's expectations.
