Linus Torvalds may have called OSX "a piece of crap" too but it's actually the other way around when you compare the two, especially on the desktop. If you weren't so infatuated with foreigners and leftists like he is it would be obvious, but sales figures (how much someone is willing to actually pay for something vs. have dirty old uncle dick give it to them for free) tell the story you refuse to admit.
You always have a problem with warping facts. He was referring only to the free-software Mach kernel (not GPL, made by Carnegie-Mellon as a research project), and that was in OS X 10.0, which was pretty bad. Mach is still the reason for the performance problems I mentioned. Torvalds also personally prefers big, fast monolithic kernels as opposed to microkernels as Mach is. He even had a famous argument with the author of Minix over this design philosophy difference.
Personally, I can see both sides to the debate. Monolithic kernels are faster, but they're harder to debug, harder to port and inherently less robust. The big picture is that Mach made it easier for Apple to smoothly transition to Intel.

I'm infatuated with good software. You are the only one on this board infatuated with these people. You are the one who usually brings them up, as you did in your first post to this thread. Nobody had even discussed Torvalds or Stallman on this thread until that.
