APL is fine for normal humans, if they are introduced to it early enough. Like, And RPN is what makes Forth, and stacks in general, so darn useful and so easy to understand the internals.
RPN and buttons. My first bought it as a daily carry back when eventually succumbed to key failure a few years ago. First one defunct from use and abuse , as well as my original 35 and a 35S now my daily carry.
I love a physical calculator. Have you tried PhyxCalc[1]? If for no other reason, hex conversion. So the 32s stays next to the laptop. Seriously though, you just say display. I started one myself not too long ago.
My daughter was once engaged to an engineer. A while later I asked what you found out. Years ago I was taking a Pascal class. One of the homework assignments was to write a program for a 4 banger RPN calculator. On a good infix calculator, like a TI89, if I realize I made a mistake in a complex calculation, or just want to change a number in it, I can press the up arrow and edit the calculation.
Do the newer ones let you do that? They always have. Instead of entering the calculation in immediate mode, you enter it as a program. A valid point, though analysis of Forth algorithms shows that a 16 deep stack is very rarely exceeded. The three register choice is also odd given what HP had demonstrated so well about 4 registers. A calculator is the perfect base for smarthome control just like phones were the perfect integration point for everything else.
I think walkie talkies are probably one of them, imagine FRS over ZigBee with multi-week standby battery life! There are copies on the various online libraries. A physical copy has become quite rare and expensive. I bought an hp48sx back in the day. Still have it. I no longer love my hp48 as much!
On hp48, you need to create a dir, create an equation, save it in a var, repeat, enter solver menu, enter var you want to solve for, press solve. Any Android RPN calc apps that work with physical keyboard? Please be kind and respectful to help make the comments section excellent.

I think I have replaced batteries twice in 32 years. I use Free42 on my phone. Free42 is also what I use on my phone and computer, I also still use the real thing.
Pure prefix or pure postfix makes much more sense. Lisp is a beauty and so is Forth!
