Actually I think raja doesn't deserve all the bashing that I've seen on the web. He's done some good too!
If we turn the clock back, Intel had to completely scrap the Larabee project after pouring in billions because it under performed. Well, in reality, it was a total disaster!
Their iGPUs have been stagnant for more than a decade with tiny incremental updates that aren't even worth a mention.
Raja started with a clean slate, cut out all the old crap, delivered decent hardware (not top notch but still good) and most importantly intel now has super stable and clean graphics drivers because of his past efforts. That itself is a humongous task. He did take his own sweet time, but without his knowledge and experience, Intel would be having another Larabee in their hands.
Instead, now they're in a position to compete with AMD/Nvidia/Apple in the lower to mid-range graphics which by itself is an massive achievement. In spite of delays, Raja still deserves a little bit of our appreciation I think.
