Windows 8.x growth flatlines, Internet Explorer 11 makes a splash

November was the first full month of availability for both Windows 8.1 and OS X 10.9. After the initial surge in October, Windows 8.1 increased its usage share of the Web by fifty percent. OS X 10.9, however, almost tripled its share—bringing Apple’s operating system within spitting distance of Microsoft’s.

In the browser space, the launch of Internet Explorer 11 for Windows 7 (as an automatic update, no less) has seen that browser more than double its share in a month.
