Thirty years later, the question is: when will it no longer work for our needs? According to Harms, because of the memory limit, the 12c's date calculator can handle dates only up to.

The HP 12c was expected to last just a few years on the market. To everyone's surprise, everything sold out at launch. The bookstores ordered 4 million units of the HP 12c, expecting to sell just 1 million. At the time, because of the common lag between ordering and production, retailers tended to order about four times the number of products they expected to sell immediately. According to Harms, the product was first ordered by college bookstores. Still, the success of the 12c has gone beyond the expectation of HP, which in the early '80s was still focused mostly on test and measurement devices. 'They told us not to screw this up and that we're not going to introduce this thing until it's ready,' Harms said. As he recalled, previous generations of HP calculators hadn't done so well and the upper management told him and his team to take their time to make the product as good as it could be. According to Harms, the 12c is also an example of HP's emphasis on quality at that time.

Harms believes the reason why the HP 12c is still in use today, despite the fact that all smartphones and personal computers include a calculator app, is because the device just works, and works instantly without loading time. The HP 12c is also one of the first devices that uses CMOS for its circuit-board and 10-digit registers as its memory. 'The processor itself computes in decimal, instead of binary, making the calculation very accurate and fast at the time,' Harms said. This allows the product to last for years on just two miniature replaceable batteries.

Essentially, the calculator has only three main parts: the processor, the RAM ROM Display Driver chip (aka 'R2D2') and a digital clock. However, the design is one of the best parts, according to Harms, because it minimized the amount of components inside. This cuts down the time a user has to work on the keypad.
