PARC _was_ Xerox.
I know PARC was XEROX, the part of my message you edited out clearly says
that. The quote you misattributed to me was Arnold's.
The concept of having a graphical front end as the
main user interface was
not from the Alto, and the Alto didn't have icons
either; both came later
(I'll let the Lisa people and Star people argue that one out).
Yeah, well they can argue, but it's pretty clear Xerox came first. Of
course, neither the Star or Lisa were really full fledged commercial
products, but one might argue they are both Alto follow ons. Jobs had seen
the Alto at PARC before Lisa was very far along.
