In a recent interview with CBS, Bill Gates talked about his work after retirement and commented on Microsoft's recent performance. On the topic of Windows Phone, Bill Gates said that the strategic deployment of Windows Phone was a mistake. In this interview, "we didn't miss the mobile phone market", Bill Gates said, "but what we did in the past didn't make us become the leader of the industry, which is an obvious mistake."

At the 2011 financial conference, Ballmer, the current CEO of Microsoft, claimed that Windows Phone would become the third mainstream platform in the market. However, according to the latest data from comScore, in the last three months of 2012, the share of Windows Phone phones has continued to decline, only 2.9%. Less than half of the blackberry that has always been sung off.

From the current perspective, Ballmer's commitment to become the third platform of the mainstream market may be a remote and unattainable mountain. Will Bill Gates go out of the mountain to escort you?
