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

The usual extreme evangelism usually reserved for operating systems.

Important requirement number 1 for me: enters and displays results in engineering units. But even thats not essential.

There is no single tool for everything, being open minded and using the appropriate tool for the task to hand is far better....

Why no RPN spreadsheets?

I use regularly a Casio fx-991ES

This thread made me check on availability of my current fav. And damnit, they don't make my model, anymore. The new Casio 115 is slightly different, using the oval buttons and screen and sliding cover of the 991, which I also have. The screen is an bigger and has more resolution for displaying weird stuff (but the contrast is not as nice; the old 115, the background is perfectly clear; you can see the background partially darnkened as soon as you turn on the 991). The other two things, not so much, IMO. The oval buttons don't stay aligned and will sit crooked. And the cover is not as easy to use as the old snap on/off cover.  :'(

Do you find any of those few extra functions in 115 useful? For those who are not familiar, brief intro of Casio 991EX by Dave.

^Honestly, I don't use a lot of extra functions, but I'm pretty sure the 991's do nearly if not everything the 115's can, plus a lot more.

There's just a few things that I had gotten used to, I think. The ergos. And the way in base (dec/hec/bin/oct) mode, my 991 fills all the spaces to the left with zeroes, for god only knows. Especially with binary, it means you sometimes have to scan a few extra spots to the left to make sure you are reading the entire number. It's better left blank, IMO, the way my 115 does it.
