In a surprise twist, smartphones running Microsoft’s old mobile
operating system grabbed more market share than new Windows Phone
7 devices did in the U.S. in the fourth quarter, according to data
released by the NPD Group research firm this morning. Devices
running the legacy Windows Mobile registered 4 percent of the U.S.
consumer market in the quarter, down from 7 percent a year
earlier. Windows Phone 7 debuted at 2 percent.
Windows Phone 7 devices weren’t available all quarter long, and they still aren’t on Verizon, but this is bad news for Microsoft.
