Engadget's got a story posted up with a video that shows how easy it was for security company F-Secure to brick a PSP. Crazy stuff.

"If you were ever curious as to exactly what was entailed in a PSP-bricking (for the uninitiated, that’s when running some code that kills your PSP entirely), famed antivirus company F-Secure (who we hope you should well know by now) plunked down the $250 to do an on-camera bricking, for, um, educational purposes."
