That sounds like a good summary. I started out on TI programmable
calculators (my first was a TI-57 that I still have, and that still
works), but moved on to RPN with an HP41CV. Today, I find entering
calculations into an RPN calculator simpler, because I naturally think
in terms of the stack. With a traditional calculator, I have to look at
the (possibly just mentally imaged) formula that I need to evaluate, and
type it in character by character, whereas the RPN calculator lets me
think about the calculation to be performed, and just enter that.
