Darling_Jimmy: Well, I meant the seemingly misplaced hostility.

Wasgo: You're absolutely right that Macs don't play the games as well. When the first generation of Boot Camp was released, many Mac users posted about how it was beneficial to use the Windows versions of games like Civilization IV rather than the Mac port, because it had less bugs and ran faster.
As for the upgrade problems, it doesn't matter which platform you use. Whether it's hardware incompatibilities with Vista, or 32-bit input managers causing errors in Snow Leopard, these things happen. It's always funny how the argument gets focused on these fringe scenarios rather than daily use. For me, I find that my Mac is more useful for web browsing, e-mail, task management and other similar task. For gaming, it's either older games or I play on a console. Neither Mac OS nor Windows are 'better'. It all comes down to usage, preference and past experience.

WhiteHamster: The big horror stories you hear about people with their games breaking are from pirated games, which really irks me. It's never games that can't be found anywhere to buy legally (Baldur's Gate) it's games like Batman or Crysis.
