Of course, as you point out right at the end, you can't please all the people all the time, but I think it provides a good overview and will be useful to motivate and encourage folks to check one out in more detail.

While I did find myself saying RPL aloud when you called the 28/48/50 RPN, for the intended viewers of the video, "RPN" is close enough for these purposes; wouldn't want to confuse them.

Thanks for taking a LOT of time to make this and share it.

I think there is some confusion about RPN and RPL.

IMHO , all the 28, 48, 49 and 50 series are RPN. Because RPN is the way you enter operands and operators, postfix in this case. There's a difference in the way ENTER function in these calculators, but they are still RPN (postfix).

RPL is a PROGRAMMING LANGUAGE, that is available in the mentioned calculators.

The others HP calculators use keystroke programming.

Resuming, HP 28, 48, 49 and 50 series are RPN calculators with RPL programming language.

Just my 2 cents.

Live long and prosper

Cheers
