What calculator do you use ?

SingedFingers:
Bloody hell. I've got one of them as well somewhere!
WattSekunde:
My first and all time favorite RPN was the HP 48SX. From time to time I use HP 15C LE and the fully self resaturated HP 97 on my desk.  ^-^
It's also very handy to have them 1:1 on my touch devices with me.

Non RPN calculators always confusing me.  |O

An actual HP-11C and I use the RealCalc app (pictured) in RPN mode on my Android phone.

Kilrah:
Still my old TI-89.

I never had a 41CX. I went from TI 57 to HP 28S in 1986, which I still use today.

Though frankly, most often now my "calculator" is google. You can do all kinds of things from the google search bar, including any kind of unit conversions, decimal/hex/binary, up to the minute (nearly) foreign exchange rates

Being able to copy&paste from or to what you're working on, rather than enter again on a physical calculator, is a huge timesaver.

Enter: 9.8 m/s^2 * 3 s
Google: 29.4 m / s
Enter: 9.8 m/s^2 * 3 s in km/h
Google: 105.84 kilometers per hour
Enter: 100000 aud/year in rubles/month
Google: 358 043.617 Russian rubles / month

It's pretty useful.

If it's more repetitive/complex then my calculator is OOcalc or ruby/perl. Hmm.. or actually I use elisp for quick calculations a *lot* too. All depends on what is handy and convenient at the time.
