You *did* do a format and reinstall, right?

I'm on an Intel Mac at work, and it reaffirms to me the basic mundanity of the universe. It's making about the same issues-per-hour my old XP box at home is. Ever had the Terminal app lock up? The system won't restart, since it can't stop the process. Force quit doesn't work (although it "helpfully" removes it from the list even though it's not really zapped) and forget using Sudo and the command line... because Terminal's broken. :P
