>What happened? I don't get it either. Even if HP lost interest, why didn't anyone continue with RPN (patents, maybe?). I think RPN is both better for learning at school (you see intermediates, and you learn operator order), as well as general use. I love that you can just get stuck in calculating without having to worry about getting it all in the right order at first. I'd love my children to use RPN when they reach that age, but there is a lack of RPN calculators on the market, a lack of knowledge at school and it may even be banned by the time they need to take an exam.
