OS X very much supports SMP ... and it uses it very effiencently ...
however, applications you use that are not multithreaded do not split
threads between processors, so the OS splits processes but the threads
remain clumped therefore the benefit is reduced in comparison.

All very valid points too, but you actually hit the nail on the head
by saying "For video rendering...." that's the whole point, by and
large the Mac OS (9 or X) have not been written well to optimise or
use twin processors efficiently ALL the time, so what's the point of
Apple shipping MP machines if you are only really seeing in a day to
day situation only about 20-30% increase in performance when you
should be seeing nearly double the speed. This is real world stuff and
not task specific. Too me it's the whole MHz myth a dual 2.0 sounds
like it should be like a single 4.0 but it aint.
Yes I would like more RAM as I too believe an absolut min is 512 for a
SOHO machine, 1 gig preferred but 2Gig ideal and it will come, still
got 4 slots empty, but $$$ are the consideration.
