Right now, I've got Linux and Windows on seperate partitions. While the kernel is always stable, all the Linux distros I've tried have been buggy, and I'm always wasting time on trying to get something, like setting up a DLS connection, to work properly. How does Mac os x compare? How are the X programs that matter to Webmasters, like Perl, PHP, etc?
OSX runs Perl, PHP and MySQL as well (PHP and MySQL are simple to install). You can also set up virtual hosting, which is great for developing web sites - I just browse to http://clientname/ while working on a site.
Among my machines one is 100% RH9 I got rid of MS and installed Linux that one machine is quite not a young chix :) Full case Micron built (2000) only a pent3 @450 which was just about top notch years ago
Anyway I chosen the custom install and installed everything the only requirement was to start MySQL and PHP the rest works on auto your only further install will be PHP my Admin that does not come bundled with any **nix flavors
now I have the same setup on a recent home built with modern power and RH flies like a "racing formula" <owner edit: Typo />
