HP Ends Calculator Development. I don't know what the current state of the engineering calculator business is, but it was fantastic to see our Calculus class in high school all use HP48G's. It was also interesting to beta-test those fancy TI models that do all the integrating work for you, and realize we wouldn't have learned nearly as much about mathematics using them.

I still love my HP48G (I have the GX), and have all the programming manuals and even an IR thermal printer. I don't use it much, but I still love it. Long live Reverse Polish Notation!
