I stay far away from Macs. Everytime I've used one in the past couple years it seems to have a 6th sense of when to crash to inflict the maximum amount of pain on me.
BTW: OS 10 is not UNIX based, it is based on BeOS. They are not the same OS, they just look similar. (There are tons of OSes that were influenced or based on UNIX. I can think of Posix, Minix, Linux, "Unix", HP-UX, Solaris (in all it's flavors), BeOS, Mac OS X, Windows NT (believe it or not), uClinux, FreeBSD, and more.)
