Mac OS X Grabs Record Market Share

Apple's Mac OS X operating system grabbed a record 7.57% of market share in January, up 21.7% from the year before, Fortune's Apple 2.0 blog reports. The computer company’s share grew 3.56% over the course of December, while rival Microsoft Windows faced a .36% loss—though it still holds a wide berth over Apple, with 91.46% of the market.

“Apple’s market share gains in December for the Mac and iPhone are impressive,” says the study on which the report is based. “However, for the last days of December”—when Apple's share reached 8.01%—“the numbers are nothing short of spectacular.” Net Applications, which released the data, collects information on visitors to 40,000 client websites and bases its numbers on usage rather than sales.
