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.

As a Middle-Aged person who does math on the periphery of calculus reasonably often, for work and in my day to day life, my irritation with calculators is that their capabilities are largely driven by the education markets demands. The small handful of calculators with CAS abilities are usually kneecaped to what would be allowed in a testing environment.

I want a calculator that can do all the transforms for me and show the work so I know what I'm doing.

For my day-to-day needs I literally run a TI-89 emulator on my android phone these days. Seems silly.

Mathematica?

My thought exactly, or Maple, if you are one of THOSE people.

It's a lot of money and isn't a standalone device.
