This is interesting stuff. Some if the things I read in the late 90s and
early 2000s seemed to suggest that the Linux and BSD type platforms were
antiquated.
Probably FUD.
But Apple is still moving forward and further refining and updating the
OS X core.

"There is a lot of confusion about the fact that Snow Leopard starts
by default with a 32-bit kernel even though nearly everything else is
64-bit (according to Apple all system applications except DVD Player,
Front Row, Grapher, and iTunes have been rewritten in 64-bit)."
"Snow Leopard is 64-bit for all users with a 64-bit CPU. The
applications are, the memory space is. The ONLY THING that doesn't
load into 64-bit - ON PURPOSE - is the kernel!"
"The problem is compatibility with third-party drivers. Some programs
are so deeply intertwined with the OS that they reach deeply into its
bowels and modify its core, the kernel - these drivers are called
kernel extensions (or kext)."
BTW, the new Mac OS ships this Friday.
