Microsoft CEO Steve Ballmer has never been one to mince words, and the executive shared a few choice thoughts on Google’s Android platform while speaking at the Web 2.0 conference on Tuesday. “You don’t need to be a computer scientist to use a Windows Phone, but I think you do to use an Android phone,” Ballmer told Federated Media founder John Battelle during an interview on stage. He continued, “It is very hard to be excited, for me, about the Android phones.” Despite the platform’s innovative user experience and its slick UI, sales of Windows Phone handsets have not been impressive thus far. Microsoft has been hesitant to share hard numbers and partners have followed suit, but recent estimates suggest Microsoft’s share of the smartphone market may have hit a new low in the second quarter of 2011. Nokia is expected by many to be the catalyst that helps establish Windows Phone as a major player, however, and Ballmer confirmed that Nokia is set to unveil “a bunch” of new Windows Phones at Nokia World next week.
