Fortune magazine's Apple 2.0 blog reports that Apple's market share grew sharply in December, as measured by a Net Applications survey released on New Year's Day, reflecting strong holiday sales of both MacBooks and iPhones.

According to the survey, Macintosh market share rose from 6.8% to 7.3%, while iPhone use on the Web rose from 0.09% to 0.12%, suggesting that one out of every 1,000 Web surfers is using an iPhone to browse the Web. That's a 33% increase.

Curiously, the survey makes zero mention of other cell phone platforms, such as regular feature phones, BlackBerrys, Treos, and the like. We'll report more as we hear it, but something looks fishy in those results.
