lol, who hasn't?
I've dropped my GBA SP countless times. I once dropped it on a hard concrete floor, which damaged the speakers, and thus the sound no longer works.
Back when I had my DS Lite, I dropped it a couple times; however, I tended to take really good care of it, so it never got too damaged. Until that one time it fell out of my pocket while I was walking to school and... well, I never saw it again!
My old 3DS never got dropped, which is surprising considering I always had it in my hand, even when doing stuff like getting food! Of course, my friend later "dropped" it outside his house... honestly, I think it's more likely that he put it in front of his truck tire himself...
My new 3DS XL, since Christmas, I have dropped 3 times. The first time, it was still in the box though. I haven't dropped it since last year though (20 days ago XD) because I do take good care of it, because I have no intention of letting it break.
