Say, someone invented a calculator keyboard that can snap on top of an iPhone.
It had real keys, not the fake glass surface simulated keys.

For all practical purpose, it is same as the real calculator, only much faster.
You snap-on a HP-15C keyboard, you get a HP-15C ...

Does that meant the end of calculators ?
No, we just rename the new gadget as the calculator.

BTW, I checked before posting.
Snap-on calculator keyboard not yet exist :-(
