Hi Jay,

I consider this a speed issue too.   I concede the quantity issue,
they do more things and do them all faster.

All parallel programs compare poorly to serial programs by this

I agree on this too.  I think they probably felt a lot of
frustration during the whole ordeal but I'm just guessing.
Beating Kasparov must have been sweet for them.
