We've been seeing posts and vids (and getting tips) on a program called iAlertU all week, but were a little skeptical of software that claims to use the tilt sensors and camera in your MacBook Pro for triggering an alarm if someone tries to snatch your lappie. Skeptical, that is, until a beta version of the application was released today,. While feedback so far indicates that the code is still pretty buggy, the program seems to actually work, with users generally pleased about the overall operation (for the five minute usage limitation of the beta, anyway). Developer Slapping Turtle says that once all the kinks are worked out, a non-time limited version will be available for $10, which seems like a good deal once key features are implemented -- most importantly, headphone jack and other overrides, because even the most dim-witted thief may somehow stumble upon the "force restart" key combo in mid-heist.
