I certainly do wish such an updated model were available. More memory perhaps and the Cash Flow functions of the HP17Bii would have been very handy. Seems like adding RPL would have been natural given it already has a four level "answer history."

Having recently left the rat race, I spend more time calculating returns on investment than inverting complex matrices! With the manual at hand in physical rather than PDF form, plus Martin Hepperle's excellent article on the Solver, I'm trying to reproduce some of the missing features I use on the 17Bii. Maybe throw in a few logical function to complement Base arithmetic too.

The 27S is a really great scratchpad calculator!
