Is RPN still relevant?

This is the main advantage of RPN over everything else, calculator-wise, in my eyes too and beats crosswords and sudokus big time! I enjoy trying my luck at Valentin's calculator puzzles or those from the conferences posted here (usually weeks later and with little success, therefore I don't post results...). Most of them would be trivial to solve on a computer using any programming language or a modern calculator with CAS or a Rasperry Pi that comes with Mathematica, therefore these solutions are forbidden.
But it is RPN and the very limited number of storage registers and program steps that turns them into a big challenge. Or, similar to how President Kennedy once phrased it: "We chose to solve our puzzles using RPN - not because it is easy but because it is hard!" :-)
