Lisa
Actually only Jobs went to PARC and he was dragged there by Jef Raskin. Apple leased the STAR technology to build the Lisa (named after his 1st daughter). The Mac used ideas from STAR, but took a completely different approach. Another point always missed by pundits is Apple was already working on a Lisa and Mac project before Jobs ever went to PARC. Jobs loved the GUI, but missed the OOP and Network side of STAR. Gates only understood he needed to counter Jobs. His Windows was, and still is shit, but he made it successful so hats off to him. Another point that is always missed is after Jobs left Apple and founded NeXT, his OS, SDK, and networking all are part of todays OS. MacOSX and laier IOS is the evolution of NeXT. Now that Steve is gone, the tech industry has gone flat. Bigger screens and a faster chip are fine, but nothing is new and exciting anymore. I just hope F1 can see this and dump that hybrid crap and build great cars again. Green cars, like bigger cell phone screens are going to move things forward.
