He was probably the same DEC marketing dwid who said last year that
HP was "up against the ceiling" in performance.  We "just took old
technology and pushed it to the limit."  Well, it worked last year and
it worked this year.  Anybody want to bet against us next year?

When are marketeers going to stop projecting the limits of what engineers
can do, and just let us get on with doing it?  Get over it, people.  Stop 
predicting who's out of gas and look forward.

Surely.  Or not.  If it's the right thing to do, you can bet we'll do
it.

You did an excellent job of explaining why the junior architects' club
doesn't design VLSI chips.  They can sit back and handwave all they 
want, but the proof is in the product.  

Can't anyone understand that the 21064 and the 7100 aren't blazing fast
because the architectures are great, but because the engineering was
great?  I'm sure the Alpha design team could have built a MIPS 
architecture chip that performed just about as well as Alpha if it
suited their purposes.
