Virtual memory is not the type of software some self-taught programmer
can knock off in a weekend with a couple of pots of coffee :-) In
fact, most self-taught programmers probably couldn't hack the problem
at all.  Ask someone with a C.S. degree whether they think it would be
challenging to retrofit an operating system AND applications with
virtual memory.  Ask them "When has it EVER been done before?"

Furthermore, nobody believed that VM could be implemented so quickly
on the macintosh, once there was a PMMU.  Well, Connectix has done the
R & D necessary to solve the problem.  They should be applauded.  $295
is cheap when you think of the risk they took.
