Even for simple calculations, speed brings comfort. I enjoyed the 15cle over the original one for that.

I agree in case of a top level graphing calculator, like the 40G to 50G comparison, but I don't think the 32SII is a slow calculator for a daily "napkin numbers" use. And it is quite a capable machine for this use...

Speed is not only for execution of programs. It is also simply the time between key press and reaction, whatever it is. As I said I saw a big difference between 15CLE and original 15C and if it is really a matter of few ms, it does bring comfort. The original 15C feels very sluggish for our today standards, like you press a key and the LCD slowly refreshes.
