This video from four years ago turns out to be a really good de facto promotion for RPN calculators without even mentioning RPN (except by implication in the last few seconds)

Dave's Take

During my career I moved directly from a slide rule to an RPN calculator when the time was right and never looked back (or sideways).

I’d be very interested to learn what the good people here use as their goto calculator (RPN or Algebraic).
