Umm, news to the Register: in elastic markets (like computer chips) sales typically do go up as prices go down. That's a result of this thing called "economics." In fact, and this might come as a surprise to the story's writer, companies sometimes actually lower prices on purpose to increase sales.
Read the story. It actually states that, although sales were up, chipmakers were hurt because prices were lower. I don't mind a little ignorance in a journalist, but man, this is a doozy.
