Not too long ago, there were reports that Apple's market share was stagnant, and that throughout most of this year it had been flat. Various reasons were put forth, such as the transition to Intel, issues had with the first generation of the new machines, lack of key universal binary applications, and others. Today, after Apple's spectacular quarter, talk of Macs going stale and market share being stagnant seems almost funny.

In the US, according to Gartner, Apple shipped 975 units, significantly more than the 744 shipped a year ago. This puts Apple's market share at 6.1 percent at a growth of 31 percent year over year. Worldwide, Apple is looking at a modest 2.7% market share.
According to IDC, in the US, it has a 5.8 percent market share and 2.8 worldwide.

The number may vary a little because of different methodologies, but the writing is on the wall… Apple's sales are growing constantly. This is truly great news, especially considering that all the reasons put forward for the possible flattening of Apple's market share are still true. When the Transition is truly over, and Leopard hits the shelves, and the portables get refitted with Core2 Duo processors, sales will really go through the roof.
