Opposite story here... I still use my TI-89 (or my even older TI-86) from time to time, even when sitting in front of a PC that has R, Maxima, Gnuplot, Axiom, Sage, etc. installed. There is something about the format of those old TI calculators that I find oddly appealing for whatever reason.

That said, when I don't have a hand-held calculator handy, I usually just fire up bc or R when I need to do some quick calculations.

Those who prefer RPN should check out dc! It's my preferred calculator for simple calculations.

If you're using bc for the first time, be aware that you almost certainly want to run bc -l -- otherwise no decimals will be displayed and you'll get whole number answers to everything.

The -l flag changes that behavior to instead use 20 decimal points.

An arbitrary precision calculator language. It can be used as a scripting language or from an interactive shell. It is part of POSIX so you are running Linux you probably have it installed.
