In this article on Yahoo!, Bill Gates takes a jab at Apple. Its only a few paragraphs (the rest of the article talks about Xbox 360, overtaking Sony, and stock options, etc). Is that last comment (bolded) really supposed to be a jab at Apple? Sounds more like a jab at his own OS. My answer to Bill G. : Yeah, they will work on the Mac and won't on the PC. UPDATE This more complete interview with Bill G. reveals that on May 2, he had already gotten his grubby hands on a public release of Tiger.
