I work on PCs and Macs...and I am not interested in an OS debate...but I will say that I did a marathon job where I worked two hard core weeks in OS X running FMP, Entourage, Word, AIM, Excel, iTunes, etc...and I never had the system crash once. In fact, in a year of X, I've had only one kernel panic and that's it. I hear XP doesn't crash often either...I have it but haven't used it yet. I've been lucky so far...I keep archived copies regularly...and not the same copies in case one may have become corrupt. But I hear your pain...it has happened to me a few times in the past.
