What's the current go-to calculator for electrical engineers?

Sal Ammoniac:
I've got two vintage HP-25's here, but the batteries have long ago failed to hold a charge and I can't find replacements, so they're just paperweights now.

Does anyone use a HP Prime and can report whether it's good for EE?

I use the HP Prime.

I chose it above all because of the excellent keypad (RSI issues require this), but I’ve been doing well with it for my electronics apprenticeship.

It does some things extremely well (like using the touch screen to easily select prior results or formulae to copy them into a calculation), others could use improvement (like the brain-dead engineering notation implementation). Overall, I’d say it’s a very, very productive calculator to work with.

Pictures don’t do justice just how much smaller it is than the TI nspire. It’s a gorgeous piece of hardware. It’s really no thicker than a typical non-graphing scientific calculator.  (It is actually thinner than my TI-30X Pro MathPrint!)

The latest firmware for it added Python support. I’m curious as to whether that will lead to more apps for it; there aren’t exactly a ton of them now, and they’re not especially exciting.

I also use the HP prime, but finding programs for it is a bit harder. Do you know if there is any website dedicated to it?

They are, but suffer from the same issue that oscilloscopes on a PC have: there is nothing like stabbing actual buttons. I can type in a problem on a calculator far quicker than I can point to the keys on a PC,

Uh. A computer keyboard is infinitely more comfortable and faster to type on than any calculator's keyboard, unless your computer keyboard is utter crap, in which case, ditch it.
But seriously, if you can type faster on a calculator, good for you. I've never seen that except maybe for old people these days - maybe you are, and that's ok!

I think it's not that simple. Yes, a computer keyboard is faster to type on, but you're either looking at the keyboard or the screen. I am pretty sure you can't touch-type the shift-key'd cosine function on the PC though, so you're looking at the keyboard for that (assuming you can remember where it is). On the calculator it's a one-finger stab job (better for not getting digits out of order) and you can see all of the keys and all of the screen at the same time.

And, like I said, you're not interrupting whatever you were doing on the PC - switching to the calculator app then back to whatever it was and making sure the cursor is still where it was is not an instantaneous thing and probably takes longer than the calculation.
BigBoss:
I've been using scientific calculators since 1977 and I've used many such as Casio P3600, FX750, HP48GX, TI-nspire CX CAS ( actual one) etc.
Finally found the best one. :)

It's only 2.89 Euros for all kind of math computations.
