Personally I seldom use calculators. For simple calculations, my brain works faster, at least faster than the HP48 used by my German manager last time. If I do need to use calculators, I do not need to use any fancy ones. Most often, Windows Calc works. More times, a cheap calculator from Casio/Sharp works for me. On the other hand, some people can not work without their RPN calculators. I've several colleagues who liked their HP48/HP49. Last time they got me interested and I install the emulator on the PC and the HP PDA. But I could not stand it and then delete them.
