I've said it here before, and will again, Keller is THE man when it comes to chips. If you study his work history, and respective company achievements, nobody comes close. I'm sure others are involved and I mean not to take away from them, but if you want to lead the chip business, you hire Keller. Secondary, this appears to be his MO from an outsiders perspective. Once he has finished what he started, he seems to bounce. Not sure if it's his style, or if a different company throws more piles of cash at him, but it's interesting to watch.
