My DS's are pretty run-of-the-mill.
I've got a classic silver Phat, with a broken hinge. Still playable, mind you.
Then, I've got a boring ol' white DS Lite with a touch screen that's permanently off-center (no amount of calibration will do the trick). I got it at launch, so it's got the old crappy control pad that never seems to want to go in diagonal directions.
Next, another Lite, the Pink model with the different-feeling control pad that makes going diagonal easier. But it's mic is out.
FINALLY, a black Lite. Like my white one, it's an older one with the cruddy control pad. This is the only DS in my whole house that hasn't broken in some way. But now, having said that, I'm sure it will get busted for sure somehow.
In short, DS's beware, stay away from my house, lest you be damaged.
