So, basically everyone is saying:

If you need your AS/400 with interactive support, you pay X dollars for the
AS/400 and X dollars for the interactive hardware.

If you don't want the interactive functionality, you just pay X dollars for
the AS/400.

It sounds rather similar to the old 386 and 486 days.  You paid X dollars
for a CPU and an FPU and you paid less with the FPU disabled.

So Intel had a "FPU tax" in place? :)

Am I following this correctly?
