He puts forward the idea that Steve Jobs is executing a 'scorched earth' policy in order to kill Windows.

Interesting, but I don't think Steve Jobs has been that obsessed with Windows for a long time. I do agree with his final point though: this is not the end of Microsoft, rather the beginning of a rebirth. Yes, Apple will probably take much of the consumer space over the next ten years, but the question is which company is providing the backend services that will enable them to do it?
