I have an HP-15C that I bought in 1986, in the summer, so approaching its 35th birthday. That RPN saved my behind on many a thermodynamics test, interpolating is so quick on them. I also have an HP-15C on my laptop (and a working version of my Pickett N4-ES slide rule that I troll new hires with - "Uh, what's that you're using there?"). And, of course I have an RPN calculator on my phone. But we're off-topic.When my HP48 dies, I may have to retire. It has the most perfect buttons, no one else has even come close. And the RPN is sufficiently strange that no one under 30 can use it.
Sad but true, my poor, beloved Pigasus after a partial 'chute opening and hard landing on a parking lot. Very sad and oh, too true... I must repair to the Techiques forum for repair techniques! Don't fly plastic 'chutes in the cold!
