Just to add a few more cents to the thoughts already put forth: Note that
while NT may be fine for modest implementations, AIX offers the advantage of
tremendous scalability and an open-systems approach.  AIX is mature and robust
and industrial-strength already.  Note also the Monterey AIX effort, which
will provide industrial strength AIX on whatever Intel produces.
There is security in being a lemming, but it can be mutually-supported delusion.
