In the late 70s, places like Xerox PARC and other research labs had 
very expensive custom personal computers that were functionally 
comparable with modern Macs, if with less memory and slower. There's 
*nothing* fundamental in a current OS X environment that is 
qualitatively different from, say, what was available and possible on a 
Xerox Dorado in the late 70s, or a Sun or SGI workstation in the mid 
80s. Slicker, yes. But all of the critical ideas and techniques, 
including bitmapped displays, TeX, window systems, and WYSIWYG editors, 
were already available. I know of several early attempts (for example, 
at CMU in the mid 80s) to put WYSIWYG front-ends on typesetting systems 
that failed not because of computer limitations but for the reasons I 
mentioned.

Subsetting a language is very hard if the language was not designed to 
be subsetted. That's why it's so hard to teach introductory programming 
with professional programming languages like C++ or Java.

That might have been the case for the general public, but those of us 
who had the luck to use early Xerox D machines, MIT Lisp machines, and 
Sun and SGI workstations as part of our work around that time had a 
totally different experience.
