Otellini mentioned in one interview that Intel's projected cost was wrong, but I've never seen anyone at Intel go into specifics as to how it was wrong.

>At the end of the day, there was a chip that they were interested in that they wanted to pay a certain price for and not a nickel more and that price was below our forecasted cost. I couldn't see it. It wasn't one of these things you can make up on volume. And in hindsight, the forecasted cost was wrong and the volume was 100x what anyone thought."
