Come on, I used to work on such machines (PDP-11s, even the older VAXen) and
they were dogs under Unix.  Why do you think so many people used (use?) VMS?
It is still around, isn't it?

Unix on a fast 11 might support a compile and two edits.  And the total clock
time was comparable to that of a 10 MHz 286 with Xenix.  For that matter, I
think Turbo C would do the whole thing twice as fast with the same hardware.

AND YOU SEEM TO HAVE MISSED THE PHRASE: low cost.

Yes, and try to explain why AutoCAD takes 2 MB under DOS, 4 MB under OS/2
and 7 MB under Xenix to get the same performance.  Again, life can be easier
(as in the Mac world), but you pay for it.
