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?
