I already have an excellent HP41C emulator on my iPhone... this is not what I am talking about. It is the physical experience of holding an HP41 (or older HP2x) calculator in hands, and the feel of the keys. Nothing comes close today. Also, you could hack the HP41 with what was called "synthetic programming" ... Great fun. http://www.hpmuseum.org/prog/synth41.htm http://www.hpmuseum.org/prog/synth41.htm
