I'm glad I'm not the only one. It is perhaps more common among linux/mac users, but windows user should just join the python-as-a-calculator club.
I've always wanted a handheld graphing calculator that ran Python.
Great idea. This is your jailbroken old Android phone with Cyanogenmod and Python running in a Terminal.
Pretty much any programming language with a repl or similar makes a better calculator than any of these handheld calculator emulators
Anything emulating a particular handheld calculator will also be better than the trashy default calculator applications that are just a steaming pile of skeuomorphism.
I seem to recall reading somewhere that pg uses clisp's REPL as his calculator.
