This goes back to Clem's argument about economics. The increasing power
and declining cost of Intel HW combined with the _almost_ neglible cost
of Linux combined to kill off almost all the legacy Unixes.

That Linux modelled many things after SunOS also helped.

But I can testify from experience at my last job that AIX, HP/UX and
Solaris are all still in heavy use at major companies, mainly hosting
big database systems, but still there and not going away too soon.
