Recreation of a classic

Great app, I've had an HP41CX since new and have used it nearly every day. Now I have the iphone version I can put the real one away for safe keeping. Since its progammable just like the original, it can be handly to whip a quick program to perfrom a task 'in the field'. Has all the functionality of the original plus access to iPhone specific things like GPS. Programming is quirky for the uninitiated, bear in mind the manual for the original ran to some 450 pages.

IMPRESSIVE

Absolutely brilliant, I have two of these actual calculators, one in mint condition as a collectors item... and now this one also a collectors item! EXCELLENT
