Linus Picks Mac
Linus Torvalds makes the right choice. But before I succumb to runaway triumphalism, I will take note of this:

Torvald's response came quickly and succinctly. "My main machine these days is a dual 2GHz G5 (aka PowerPC 970) - it's physically a regular Apple Mac, although it obviously only runs Linux, so I don't think you can call it a Mac any more ;)" he said.

Yes, you can call it a Mac. He probably wanted a more stable physical system on which to run Linux anyway. Then again, even Windows emulators are more stable on a Mac than when run on a Wintel box. And finally, it is a wee bit disturbing that the Father of Linux uses a winky emoticon?
