Apple is releasing some portion of the OS as Open Source, under the
name Darwin. People are working at turning it into a whole Open Source
OS.

It's nice, but they're going about it the NeXT way, i.e. on top of
the Mach microkernel. Anyone whose used MkLinux can tell you that 
this kills performance, unless the OS on top is set up as multiple
servers (which MkLinux is not, but Apple's Darwin might be). 

Needless to say, Monolithic Linux and BSD kernels on Apple hardware
will be faster for quite a while, unless Apple does some serious
performance tuning, which they don't tend to do - according to
John Carmack on the GLX lists, they use only about half the
capabilities of their 3D hardware. Most of their machines still 
can't fill a 100Mbit/s ethernet connection.  They're probably
more focused right now on backwards compatiblility - its nice
to be able to run 15 year old binaries from a different processor
architecture, but...
