That's very interesting. I had the opportunity to work on a Lisa prior to the introduction of the Mac, and it was really pretty cool. Not a speed demon, but back then, nothing on the desktop was. Had a 68000 as the main CPU and a 6502 for the display processor, as I recall.
I liked the document-oriented approach -- instead of opening a word processor application, you "tore off a piece of paper" to start a new doc. It made sense to me. Windows has the context menu "New..." function which does a similar thing; sadly, MacOS no longer has something like that.
I went to a Comdex one year and Jobs was there, demonstrating the Next in one if the suites.
What an absolutely amazing machine, display postscript, UNIX. I was entranced.
My friend bought one, believe it or not, it still works!
But then again, so does my Quadra 800 and other Apple dinosaurs
