RE: New calculator interface
Came across this contender for best ergonomic calculator interface: Zelco Phorm Ergonomic Hand-Held Calculator from 1986.

"Zelco produced this calculator in two different models: one for right-handed users and the other for left-handed users. As the calculator’s title suggests, the device was designed to maximize efficiency and comfort for the user. The brightly colored keys, coded by function, allow for ease and accuracy when entering calculations."
