Ballmer was speaking at the 2011 Microsoft Worldwide Partner Conference, and was discussing the success of the Windows 7 operating system. As far as Windows Phone 7, Ballmer was still optimistic that it was still going to take off, stating that "You're going to see a lot of progress in that market." According to Nielsen reports, Windows Phone 7 currently has a 1% share, with 38% of the U.S. market going to Android, and 27% to the iPhone.
Windows Phone 7 definitely has some detractors, but you wouldn't expect Microsoft CEO Steve Ballmer to point that out. Yesterday he did just that, however, admitting that "We've gone from very small to very small but it's been a heck of a year."
