You hit the nail squarely on the head there. It's why I've never been persuaded by the organ/keyboard + module route. The early promise of MIDI, that no organ or keyboard would ever be obsolete, and that we'd just be swapping one "expander" (remember when they were called that?) for another, fell over the first time anyone actually tried it.
I'm always harping on about the importance of UI to arrangers. The physical proximity of all controls necessary to enable live play is absolutely essential, IMO.
