It's numbers like these that make you wonder what exactly Gartner and IDC are measuring.
In competing reports issued Wednesday afternoon, the two leading PC market research firms reported domestic Mac shipments for the second quarter of 2009 that differed by more than 200,000 units.

Almost lost in the noise of the Presidential debates, the collapse of the Dow and the milling of those new MacBook aluminum unibodies were the preliminary reports from Gartner and IDC this week that showed sharp gains for Apple (AAPL) in third-quarter domestic computer shipments.

After drifting inexplicably in February, March and April -- actually losing market share in two out of three months just when Macintosh sales seemed to be on fire -- Mac OS X recovered smartly in the Net Applications survey issued overnight Sunday.
Apple's (AAPL) share of the operating system market grew 5.69% in May to hit a record 7.80%, while Windows in all its flavors dropped half a point to 91.17%. MORE

Acer, the Taiwanese computer manufacturer that acquired Gateway Inc. last year, has as a result overtaken Apple (AAPL) in both U.S. and worldwide computer sales, according to preliminary reports issued Wednesday by Gartner and IDC.
Although the two market research firms show Apple's domestic computer sales in the Christmas quarter up roughly 30 percent from last year -- outpacing the industry average by better than 3 to 1 -- Apple's share MORE

Dueling reports from Gartner and IDC show Apple (AAPL) grabbing a larger slice of domestic computer market in the third quarter of 2007, although the reports disagree about just how large that slice is.

IDC also shows strong growth for the company, but by its calculations, Apple now commands a 6.3% market share, up from 5.7% last summer.
