just a picky side note.
Why does fortune make Unix "Unix"? Also some other notes, Linux doesn't include gcc either...it just happens to be packaged by the companies/people distributing a Linux operating system...I could make a distribution that doesn't have gcc, gdb, or <god forbid> fortune installed.
Like I said, these are picky issues, but it goes to show that anyone can poke small holes in peoples opinions. I think Mac has done a great job in showing what is possible with a Unix-based kernel...sure it may not be exactly what you expected or wanted, but it definitely is an achievement. Oh well, this is my drunk 2 cents.
