The cool thing? I know when it happened - because I run cronjobs on my work machine every 10 minutes (sar) and so I can tell when it was turned off down to a 10 minute period. It looks like they probably kicked it off by accident or something, I guess, or maybe ran out before they had a chance to grab my desktop (or just decided that it was too big to be worthwhile).
Ah well. That sucks - last thing a small company like this needs is to have equipment stolen. Why can't they pick on the big company with money to spare? (Answer: because the big money has real security. Blarg.)
