Unsurprisingly, the ds line is the least sturdy hardware nintendo has ever produced. I think I had two faulty units ever since 2004, or did it come out in 05? Whatever, its to be expected with a system you have to physically interact with. Nintendo probably happy they found a system thats prone to replacing. I have to wonder about the wii too though. Surely waggling will eventually take its toll on the innards of a wiimote, yes? Not to mention the slot loading drive and the flash wear and tear.
