since the thread keeps rolling here I might as well report two near misses
I was checking out an HP palmtop a while back, when I pluged it in it somehow decided to shoot a spiffy three inch flame in my face.... thank god this hippy had his hair tied back!!!
I've also dealt with a fritzy APC 3000 UPS..... plugged it in and turned to talk to a coworker when all we heard was a loud pop and a long sizzle... used up two fire extinguishers on that thing....
