Debunking Dvorak With Napkin Math For OS X On Intel

L

et me get this out of the way first. I think John Dvorak is great. I love his Macintosh articles the most because they tend to piss everyone off. I also like them because they make me think a lot more than articles written by apologists. However, as often as I enjoy his articles, I also find myself disagreeing with some of their content — content I suspect is there to incite thought and reaction more than confidence in their propriety. So in that spirit, I greatly enjoyed his latest editorial. In that piece, he lays out what he thinks will be the time table for Apple moving Mac OS X to Intel, as well as how he thinks it will affect the market.


As is the norm with his writing, it got me to thinking. In this case, how realistic is a move to OS X on Intel hardware by way of licensing to clone makers? So I fired up a spreadsheet and did some napkin math to see what it would take. Here are the results:
