Nah, I'd rather have the 15C.

0 to agree with you about that, but the 25c (I still have 7mine) was

then I think there could be an argument about the 12c vs 15c.

if you worked in finance or as a mtg broker the 12c was “THE” ing, but if you worked in engineering it was the 15c

I also have both those still.

today I use a 15c emulator on my phone, if I need one.

Polish calculators are just nearly impossible to use.

My very first favorite calculator looked like this...

... honestly....

I prefer the 15C, but both are great.

The sad part is what happened to HP, as they migrated to crappy bloatware-infested PCs and overpriced printers.

I have two. 45 years old and working like new. Wonderful device.

My Dad was an engineer at Bendix and brought home one of the first HP35s in 1972. He let me take it to my HS Physics class. It was a big hit with the teacher. We were using slide rules and CRC tables back then.

Correct. Best of all. Mine still work just fine.

As to calc in class, I agree. Try doing a square root by hand. It requires discipline and critical thinking — which is why we send(t) kids to school.
