Microsoft has decided to finally dispel doubts about the market performance of the new mobile platform Windows Phone 7 and officially announced the details of phones that are sold. According to the company information, for 6 weeks they were made 1.5 million worldwide sales, which we believe is a major success. The european premiere of WP7 was on 21 October and on November 8 devices appeared in the U.S.. Of course, you will not miss the comparison with sales of the iPhone 4, which for three days were sold 1.7 million units, but the WP7 is a completely new platform.
