Unfortunately, even within the AS/400 (including A/36) there are overlaps
between
types of systems.  System vs. server, any system vs. custom server, 150 vs.
A/36,
etc.

It will probably only get worse.  I would definitely agree that for an
existing S/36
customer the A/36 should probably be the first system to look at.  I have
not talked
to an A/36 customer yet that is not extremely happy with their results.

When the 'Invader' line is announced in February it will probably confuse
the issue a
little more.  Some customers will probably have a 1xx vs. server decision.

Best piece of advice is to buy as strategically as you can and try for the
best fit and
not the cheapest.
