Somewhat off topic, but If you're interested in the history of modern computing and not already familiar with the Xerox PARC [0] story, you should know that Xerox has a fascinating history of computer research innovation, and is often regarded as one of the real major driving forces behind the P.C. as we know it.

An interesting account (as well as a great deal more about the rest of the history of modern computers) is documented in the book "The Dream Machine" [1], which I highly recommend if you find this sort of stuff interesting.
