Wow. I knew it was better and better all the  time (and cheaper too, I can 
get a really computer for well below $2,000), but  didn't know that about 
the Cray-1.

Fascinating. Thanks, Marnie aka Doe  :-)

Since that time, though, the price of each successive  system has
come down, while the amount of power has continued to climb.   I'm
not sure of the exact ratio, but just a single-threaded application
on  my notebook PC (a quad-core I7 system roughly comparable to a
MacBook pro)  delivers an order of magnitude more computation than
a Cray-1 supercomputer.  An application such as PhotoShop that can
use all the power of the PC is  better than two orders of magnitude
faster than the Cray, while the amount of  memory and storage has
grown even faster than that!
