WrongSizeGlass writes "InformationWeek is reporting that Windows Phone 7 will overtake Apple's iPhone by 2015 according to IDC. IDC predicts 2015 will bring: Android 45.4%, WP7 & WinMobile 20.9%, iOS 15.3%, RIM 13.7%, Symbian 0.2%, and 'Others' 4.6%. These numbers would move WP7 into 2nd place and leave iOS in 3rd place with a slightly smaller piece of the smart phone pie than they current hold (15.7%). The author of the InformationWeek story isn't buying IDC's forecast, because of WP7's anemic sales to date and Microsoft's recent stumbles with its first two updates. I have to wonder if WP7 will still be Microsoft's smartphone OS in 2015 or if they'll have moved to WP8."
