And finally, get over this 'Mac OS never crashes, Windows does all the time'. I have found both systems to be about as reliable as each other. At least when a machine running windows crashes it gives some kind of feedback. Mac OS just shows you a lovely coloured rainbow...
I will admit, that OS 9 crashed on me quite a bit. Technically, it was Netscape 4.x that always crashed, but due to unprotected memory (or something like that), Netscape's crash would bring down the OS (or the OS would crash upon force-quit when Netscape got stuck).
I still think Windows 98 had it beat in number of crashes, but OS 9 was a pain.
As for X vs. XP comparisons, I've seen many more crashes on XP. That's not to suggest that I've seen XP crash a lot, mind you, just a lot when compared.
