I have no grudge against Macs, at least not since they incorporated the Unix backbone. I view them as more or less on an equivalency in terms of OS stability/customization/etc (Apple is now even using gcc 4.0--the renowned linux compiler--to compile their OS).
Still, Linux is slightly better suited to my needs.
Apple has been using that for a while, since 3.x. And I may be picking nits, but gcc isn't the "Linux compiler," it's the GNU open source compiler commonly used on most NIXes.
