Krugman's a smart guy about a lot of things, but he didn't get computers and the internet, didn't believe that measured productivity gains from using them were real (to his credit, he did publish a mea culpa or two years later) and I think he's just as ignorant about what differentiates Apple's products from Microsoft's. It's interesting that he doesn't understand the difference between their value propositions (Microsoft is competing, in a sense, with Google -- which sucks because Google gives away its products -- while Apple is competing with Amazon and Samsung).
