"You get the sense he could beat you up." But he's a smart cat too. Got the Cloud right. Skype, X-Box, Kinect doing nicely. Smartphone OS improving fast. The word on Windows 8 is good. Is the supertanker turning round?
Silicon Valley booms. New England declines. Thanks partly to an argument at MIT in 1950s about how to make semiconductors. Robert Boyce had the right answer, but lost the argument. He moved to California, tech moved with him
