How much has RPN/RPL spoiled you?

[Hlib]

In my country programmable calculators were made only with RPN logic. We had no choice in those days, so in 1984 I started programming on rather simple calculator "MK-54", made in USSR. I got my first HP-RPN(RPL) only in 2012, it was HP-50G. Nearly two years I spent to master this very difficult device to use it at last in daily tasks. I had a wide experience on other graphic calculators before, so not the existence of RPN, but mathematical opportunities of the calculator is more important for me. Even now I sometimes switch the ALG-RPN modes on the HP-50 depending on specific problems. But I prefer to carry out simple calculations always in RPN.
