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.

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.
