think of it as "hardware copy protection".  ;-)

Maybe Intel has finally found a taker for its "unique processor
ID" feature, and each copy of OSX will be licensed to a specific
processor.

Time will tell if they can get away with this artificial
incompatibility, or if people will figure out how to make
Apple have to compete on a level hardware playing field...

I'd doubt that they'd even consider that. Right now the OS doesn't
even require a CD key when installing.

I'm wondering though if they'll use that processor ID feature as part
of a way to sell downloadable movies for a video iPod. Use the ID to
make it so the movie is only usable on that one machine and you can
send the movies to a video ipod but you can't pull them off one.

At present I believe the movie industry is leary of online movies
because they know every downloaded movie they sold would likely find
it's way online the same day.

As I've been thumbing through this thread I don't think I've seen the term BIOS brought up. I think that is as much a part of the machine as the CPU if not more so.

What made cp/m such a widely used OS was its generic BIOS that served as an API. Only that piece needed to be coded to the metal for a successful implementation.

But we are long past the time when the only code that needed to be
_efficient_ on the metal was in the BIOS.  There are many thousands
of lines of machine-dependent code under every modern OS, all tailored
to the details of the (privileged) architecture.

And BIOS code (used mostly to support initial configuration, boot,
and some hardware-dependent error recovery) is now readily changeable,
making it an attractive hacking target.
