RE: Calculator find
The calculator usability equation:

general usability factor, U = 1 / (1 + C)

Where C is the curriculum coefficient, or the degree to which the calculator has been adapted (or messed with) to support school mathematics curricula.

C is zero for the HP15C, giving a U factor of unity.

For a Casio FX-83 GT Plus, C can be reckoned in the hundreds.
For the TI-Nspire range, current estimates for C exceed Avogadro's number.
