Compare a 15c and 41c is a bit like comparing a rowing boat and a sailing yacht. The 15c is a pocket calculator, the 41c a portable computer system. If you want an expandable system with external data storage, a printer and a huge software library, then the 15c doesn't offer much of that.

Yeah of course I know that 41c is expandable, but I did not realise that 15c was so feature full, and in general ahead of its time when it was released.

I had forgotten that the TI-58/59 had so much of the HP-15C functionality built-in (with the included "Master Library Module ML-01") when it came out 1977, 5 years prior to the HP-15C.
