You made the case beautifully. People are pretty much sick and tired of having to figure out which button/icon to push. Like it's some kind of recreational activity....... NOT!

I remember how many different ways there were to program a VCR, and PCs just increase the aggravation of non-technical folks ten-fold.

I'm a Biomedical Equipment Technician myself, and I can also add this. Even trained, skilled Physicians and Nurses only really want 2 buttons. One to make the darned thing work, and a second to stop it.
