Ask HN: Should there be new RPN calculators to replace the TI-84?

I took an exam today where only TI calculators were available. I felt I was caught between some older models where the TI interface was not quite worked out.

And I don't see much progress then trying my daughter's TI-84.

I had to look it up:

RPN = reverse Polish notation

Wow. In my day it was well-known. HP calculator ads in magazines explained RPN and why it was better.

"Magazine? Had to look it up."

When I was in high school in the 1980's, the other students knew RPN only as the reason they couldn't borrow my weird calculator.
