I was wondering, Who on the forum is using something like this, or who will use something like this if you had one?

Do you mind sharing what you use or want to use it for. 

For those who already use is, what industry are you in?

It's a bit fancier than the one I used as a student. I had a 20S, which I lost a few years ago when I put it on the roof of my car and forgot about it. I was using the trig functions to calculate the lengths of the triangular solar panel supports I was making in my garage see...

In 1997 it cost around R220. This was around 4 times more than the typical scientific calculator used in high school at the time, typically the Casio FX82 and the Sharp equivalent, both acceptable for the course I was taking:

It was a bit more capable, you could program a calculation into it, and then pretty much go "Execute program 1" and it would replay the keystrokes. It could also find the roots to quadratic equations. Neither functions I really care about these days.

I miss that 20S because it was a solid little thing. Not like the others that would spring a leak in the LCD after a year or so...
