For general purpose programming, I want to write expressions in algebraic format but for interacting with a calculator RPN is easier. It removes a whole layer of abstraction wondering what the machine is doing. I would imagine if I were young today and started with a modern multi line calculator with textbook display then that is what I would be comfortable with but for folks born before 1980 or so the algebraic calculators of our time were error prone. I have an HP 27S that is algebraic and breaks the mold of being error prone because it shows the whole expression up until the point where a part can be evaluated. Then it evaluates the inner part while still showing the rest of the expression.
