One of my favorite memories about Macs was in the school computer lab. I crashed the system by plugging in a USB with a word doc I needed on it. Nothing more than plugging a USB in and getting a stack trace. The lab monitor was adamant that I couldn't have crashed the mac because iT jUsT wOrKs and basically blue screened when he saw it.

Good times. Mainly because I haven't been forced to use it outside of labs.
