Does the HP-35S need a 'guide for dummies' how-to guide?

Quote:RPN vs RPL comes down to use case: 1) interactive: RPN, 2) programmed: RPL.

I think there is a third case: old guys who just love the simplicity of RPN keystroke programming. While I certainly recognize the power of RPL, I never was willing to spend the time it would take to learn how to use it. RPN keystroke programming is elegant and simple, particularly on machines like the 12c and 65.
