None of the Mac owners I know (besides myself) are very tech savvy

Hmmm, I'm a grad student in Computer Science and about half of the grad students are running macs. At the last few conferences I've been to, more than half of the laptops I see are macs ... and about half the remainder are running Linux. Geeks love it since we can get all of the great open source software, but with a nice, smooth, easy-to-maintain interface (I love Ubuntu, but I have to say Mac OS X is still nicer in many ways).
