You're totally right. But I think they don't see that when they buy. I think its like an impuse, they really want the PC for lets say to get on the internet, so they just buy the cheapest. In the end if it does burn up then yeh, they'll need to spend more. But its the impulse to get on the internet that drives them, say that person waited another 6 months and saved up then they would get a better one, but how many people do you know can wait six months? It sucks, if they sell something then they need to be sure it works properly.
