Slappingturtle has updated their info on iAlertU; a product meant to help protect Macintosh laptops from casual theft (by tying an alarm feature to its motion-detection capability and video camera).
It might just work as well as car-alarms at reducing theft. Or perhaps worse if Mac users are allowed to assign any old sound file to the alarm. Am I being too sarcastic?
Also seems like a great thing for playing practical jokes on someone.
