Agreed entirely. And in truth HP dropped the ball when it came to BASIC pocket computers. I'm fully aware of the many fans of the 71B here on the forum. But for me, Casio and Sharp were the innovators when it came to pocket computers. Sure the 71B and 75C had the Forth and Math Pac add-ons, which extended both machines considerably but the Japanese understood the market better, and iterated on their initial offerings far more successfully.

Being totally selfish, whilst also donning my fave rose tinted glasses, those HP pocket computers led to RPL,and HP certainly knew their market on that front (if we forget the 28C ever existed with its piffling 1-2kb of user program.RAM).
