What you see above is not a calculator. Or rather, it’s not the calculator you think it is. Rather, it is the latest software-only implementation of the classic Hewlett Packard scientific calculator, the 15C.
It gets better. This emulator runs on the iPhone, and is joined there by its little brother, the 12C (a financial calculator). Both calcs are photo-perfect representations of the originals and both run the same algorithms as the hardware versions to do the actual number crunching.
Now, the catch is the price. Although by no means expensive, these apps do cost more than the free calculator that comes with the iPhone, which will be enough to put many people off. But compared to the price of an actual second hand 15C, something of a sought after cult classic, they look cheap. The actual 15C can go for up to $400. The software version is a mere $20.
