What will kill Microsoft.

Craig Mundie:

If you want to focus narrowly on saying, as perhaps we should, "We're just a software company and we intend to make a business out of software" -- then I think his statements are true. It's obviously a little bit more complicated than that. But, at a conceptual level, the idea that software is not an intellectual property asset is something that we do not agree with. We spend billions of dollars a year to make [software]. Most of the established countries in the world accord it intellectual property status and we work hard to develop patents and uniqueness.

Apart from that, he makes some good points.
