You serious? 
I'm guessing a Venn diagram of RPN users and Rockbox users would have more overlap than a Venn diagram of RPN users and original firmware users.

While I don't use the calculator plugin I do use RPN calculators. And prefer them over algebraic calculators :o

I would say that your guess is highly probable.

I did not expect that RPN is so popular :) Is it a heritage of HP calculators?

No. HP calculators are there because people want RPN.

I thought RPN was invented to give firs year CS stupdents and example of the different tree walking algorithms :D
