I'm still running Leopard at work. (Snow Leopard is in the mail.) The other day, I came in to work to find this:

I can't complain really, my computer runs non-stop 24x7. I've spent the last year running disk intensive processes. I don't let it sleep so that I'm sure to be able to gain remote access from home via VPN. Its funny how our expectations change as we get used to the stability (or instability) of our OS. When Leopard crashes, my eyebrows raise and I try to think about what could have caused it. When Windows does, my shoulders shrug, CTRL-ALT-DEL, and go get a coffee. :) In fairness, Windows 7 is supposed to be much better and I have not used that version at all.
