I've never had problems with Nintendo controllers, except for the 64. B button sticks in, control stick goes limp. Oy. But the rest of Nintendo's products are highly durable. Moldrill dropped his DS in the snow one winter day and didn't realize. The next day he's backtracking to find his DS, and somehow finds it buried in a ton of snow. He brushes it off, and it starts right up. It still works to this day.
