Interesting. I wouldn't have thought of it that way. I think more along the situation where there's a "fault" on a chip or instruction set somewhere that a user finds and returns it. Or maybe the user burned something out. From what I know, the typical line testing doesn't test every function exhaustively, so that fault may get overlooked, until a user gets it again and tries to do sometehing with it, causing frustration and problems. I'm not saying you're wrong. You presented a line a of thinking i hadn't thought of. So I was just presenting mine in return. Not being arguementative.
