Incorrect!   The original OS X code base does come from next but apple 
has upgraded the code in 10.3 to use FreeBSD 5.0 code.  
apple.com/macosx even mentioned that when panther was released.  
Another document on apple's site i'm looking for again specified that 
the latest 10.3 kernel was in fact using only the messaging and memory 
architecture of Mach and the rest was in fact FreeBSD 5.0 code!

'Re-implementing what I designed in 1979 is not interesting to me 
personally. For kids who are 20 years younger than me, Linux is a great 
way to cut your teeth. It's a cultural phenomenon and a business 
phenomenon. Mac OS X is a rock-solid system that's beautifully 
designed. I much prefer it to Linux.'
-- Bill Joy, Wired Article 2003
