Timeless Interfaces, and how to Replace Them

Posted by: Josh Walsh in User Experience.

Since the invention of the modern calculator, one particular product has dominated the business market.  The HP 12C financial calculator.  Many manufacturers, notably Texas Instruments, have tried to innovate on this model and modernize it without tremendous success.

The HP 12C has gone through several design iterations without adding additional features.  It’s functionality was scoped well in the beginning, and it’s designers held firm against the inclusion of new features.  The interface is timeless.

Eventually though, technology catches up with us.  The same business people who swear by this calculator are now pushing hard for alternatives.

Today T-I announced their newest product.  In collaboration with HP, they have developed an astounding business calculator iPhone application.  The interface is pristine.  It looks and feels (except without the clunky, stiff buttons of the original) just like the real-mccoy.
