It evolved every year.  New chips.  More chips.  Better search.  Better
evaluation stuff.  Better book.  Endgame databases included in search.  On
and on...  just like everybody else.  It was _never_ a "static entity" as it
seems everyone thinks...  It improved each year like the rest of us.  But
they were so far out in front, nobody 'closed the gap'.  Even after being
dormant for 3 years, their speed is _still_ so far out in front of everybody
else it isn't funny.  We wow over 2M nodes per second on an 8-way SMP box.
DB does that on _one_ chip and is far more efficient on that one chip with
no parallel search overhead.  And then they string together 480 of those
things to let them peak at 1B nodes per second and suddenly our 2-2.5M (or my
7M on the alpha last summer) suddenly seems a tad "light"...
