Do you still use stand-alone ("pocket") calculators?

I use one when I happen to have it nearby. It's still much quicker to grab a calculator than it is to pull out my phone, unlock it, navigate to the calculator app and load it.

I still use my HP20S.  Tossed out my old Sharp a while back after the LCD finally leaked enough that it was unusable.

I have a lot of calculators, and I use them all the time. My favorites are the Casio FX-260, a one-line calculator that's great for quick computations; the Casio FX-115e, which is a great two-line calculator that handles fractions and square roots really nicely.  I also like my TI-36 that I bought in 1991. It serves the same purpose as the FX-260, but it has a 1/x function that doesn't require a shift, which speeds some computations up.

I have a few graphing calculators, but I almost never use them for graphing. Desmos.com is, IMO, the best thing out there for graphing functions. I sometimes use them for matrix operations, but but it's usually a lot faster to use Octave (or octave-online.com).

So do you still use a pocket calculator?

I still use a Casio fx85 calculator. Its quicker to just pick it up than start looking through the PC for one.
My biggest gripe with a handheld one is no backlight and LCD is not easy to read.

I've bought a HP 48G / 32k RAM back in the ninties. A friend of mine bought one, too and he came up with the suggestion to upgrade it to 128k RAM.



Result:


I'm also using Wolfram Alpha for some stuff (e.g. calculating integrals etc.)
