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.

"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.
