Never dropped it, but fell on it at the airport... We were taking those long horizontal conveyor belts, and I turned around to say something to the person behind me, not realizing how fast these belts travel... My backpack contained my laptop + accessories (full size keyboard, mouse, power brick), my gp2x in its case, and some batteries, plus some random junk I guess...
We reach the end of the belt seconds after I turned around (told you those things move fast), I'm standing with my back facing the end of the damn thing, come to a sudden stop, get thrown onto the floor, and end up falling onto my backpack... Now I'm not a lightweight; that's about 90 kg's *dropped* on top of a backpack full of expensive electronics. Man, I thought the laptop was dead for sure... Those big LCD screens aren't exactly sturdy, you know?
Turns out the laptop was OK, nothing wrong with the LCD, harddisk didn't suffer damage, still works fine to this day, almost 3 months later... The gp2x on the other hand, while technically better protected in its case, and not such a big target as my laptop's LCD, didn't fare so well... The case was ripped open at the zipper (easily fixed), and the shaft of the mk2 cap split open, had to buy a new one...
The morale? Electronics are sometimes sturdier than we might otherwise think... The big fragile laptop survived a fall that damaged the sturdier and better protected gp2x (albeit only slightly). So there's really no telling what will happen when you drop something, or like in my case, drop your heavy ass *on top of* something...
