No, I mean the guy that predicted Apple would be switching to Intel in the first place.
Linux is nowhere a danger to Windows or OS X on the public desktop for the near future. The user experience is too fragmented for Joe User.
You mean it shouldn't be a threat, because it's basically a crappy confusing client. But you're somehow forgetting Linux has all these fanatics that go around claiming it's better than everything else, and pushing users to use it, although I'm not sure how you could forget since we see it everyday on this very site.
Apple had ample opportunity to be afraid of Linux already since Linux has been running on PPC for a while. Linux Torvalds' preferred machine is Linux on a PowerMac.
Most users want to run Windows, and a few of them occasionally some version of nix on the same box. Before the switch to Intel, OSX wasn't an option. As for Torvalds, he just wanted an IBM chip and the right to claim Apple's software is qoute "crappy", as he has been known to do.
That's been rumor for about the last four years.

That works for grandma's Linux-loving grandson setting it up, but those numbers are tiny. It doesn't work well for where most consumer computers are sold: retail and big-name online.
Before the switch to Intel, OSX wasn't an option.
It still isn't an option unless you do some serious hacking.
