If you listen to the This Week In Tech podcast, you'll realise that Dvorak is just an attention whore. He just likes floating these ridiculous theories. This particular one he mentioned on the show saying that it was prompted by an email someone sent which seemed to make sense.

He even claimed he did some research (read: googling) and found that the facts matched up. I wouldn't even click on that link to ZDNet just so they don't get the satisfaction of advertising dollars. I wouldn't go to his blog either.
