Linus Torvalds will have inspired the wrath of Mac fans with his statement in his forthcoming autobiography that MacOS X's kernel, Mach, is "a piece of crap." Mach, according to the creator and guardian of the Linux kernel, "contains all the design mistakes you can make, and manages to even make up a few of its own."
Steve Jobs reportedly tried to hire Torvalds to work on the Mac operating system in 1997. Observers note the irony in that Apple Computer touts the fact that the MacOS X is based on Unix. Proponents of the system point out that a stable version is not expected until summer when Apple brings out MacOS X 10.1.
