Net Market Share's reports on the marketshare of Windows 8.x basically flatlined in November. Windows 8 had a marketshare of 6.66 percent in November and Windows 8.1 stood at 2.64 percent, totaling 9.30 percent, a very small increment versus last month's 9.25 percent.

The operating system share has some surprises. Windows 8's market share wasn't growing explosively, but it was at least growing. The release of Windows 8.1—an operating system that's almost universally superior to Windows 8—should, if anything, have helped stimulate that growth. But that appears not to be the case. The total share between the two operating systems (8 and 8.1) was 9.25 percent in October. In November it had barely grown to 9.30 percent.

The contrast with OS X continues to be striking. OS X 10.9 went from 0.84 percent share in October to 2.42 percent in November. This is still behind Windows 8.1's 2.64 percent—but not by much.
