The worst thing with this is that if Apple even tries to up the compatibility with Windows by the tiniest pico-compatibility-unit (such as improved SMB and such in Leopard; stuff that's been continually improved since 10.0), Dvorak will undeniably crawl out of the woodwork and go "see? I told you so!" even though he's arguing something completely different.

Dvorak's role is being a button-pusher. With very few exceptions, he's paid to be provocative, not insightful. I could go on, but just read Alastair's comment above.
