^^^^^^^^^^Also how accurate is that 2% figure^^^^^^^^^^^
It's kind of hard to gauge. It's all based on estimates. But both IDC and Gartner place linux usage above the mac, which is just under 2%.

IDC thought it happened in 2003.

Gartner says 2005. I'm more inclined to believe Gartner. I'm curious how the intel/mac thing will work out. I don't believe it'll be enough, Apple has lost the #2 spot for good.
Try googling around for additional info if you'd like.
