Hm hm! Hah hah! This makes me laugh! My family has had a... well, an odd history with the DS. So back in '04, My bro and I both get a blue DS, and I get a Nintendo skin* to tell them apart. My brother gets something stuck on the edge of the touch screen, so he jams the stylus up in there, and effectively ruins one DS. Touching in one place is the equivalent to touching about 1 cm to the left of it, so the right of the touch screen is useless, and no calibration will ever help. Then, he gets a light blue DS (still original model.) AND THEN, when the DS Lite comes out, he gets that, abandoning the sturdier and *opinion alert* more awesome model.
Me? No, I've never broken a DS, and have only ever had the original type.
For the record I've got nothin' against DS Lites.
