I have an HP graphing calculator. I never use the graphing function (there are much handier tools on the PC), but I have liked RPN since the first time I used an HP calculator. I use my calculator occasionally, but I mostly use excel for complex engineering calculations (either that or I write a C/C++ program to generate data files).
