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.

The HP Prime, though pricy, supports a decent RPN mode. Definitely for a higher level of education (CAS, programs, all that fun stuff), but approved for a decent amount of US based exams.

Pricy is relative. Looks like Amazon sells it for $125 (the SRP is $230)

As an engineering student in 1987, I bought a HP-28C. I recall it was the first calculator to do symbolic math

Original Price $235 which is close to what I paid. Adjusted for inflation $657

I think it was worth it.
