There was a...1996 PBS documentary, "The Triumph of the Nerds" that talks about the birth of the PC up to around the release of Windows 95. Jobs is still force out from Apple at the time. Very good show although it saddens me that it is now olde-timey and historical instead of contemporary information.
Anyway, yeah. Jobs stole the Mac from Xerox' Palo Alto Research Center (PARC). There's a great clip where he's talking about how they also had a computer network and object-oriented programming going on there but the idea of a GUI, a mouse, a laser printer, and WSIWYG display blew him away so much that he missed the other 2 innovations. And another bit where the woman who was told to show him around insisted on a written order to do it because they were giving away amazing trade secrets by giving Jobs the tour.
