I would agree, if it were a matter of _just_ running CP/M or UNIX on a
particular machine.  However, I feel that one can use a variety of OSes
on some hardware, and that it's useful to be capable of running all of
them.  I have two Macintosh SE/30 systems.  One has been 'torqued out'
with max memory and drive size, and runs NetBSD.  The other one is in
stock condition and runs a MacOS version contemporary with what it was
designed for.  

A well-known tool like NetBSD can be a highly useful to run on older
hardware.  You can use it to 'shake out' the hardware and prove it is
operating properly before you struggle to get something you're far less
familiar with, i.e. the original OS or other weird and cool things, to
run.
