HP-12C

A set of new batteries costs $7 at Radio Shack.
The HP-12C calculator was part of the employee welcoming package when I was hired in 1988. A marvel of design, compactness, and functionality for its time, the HP-12C became the "de facto standard among financial professionals."

Even today many seasoned finance executives prefer estimating the economics of a deal using the HP-12C over using computers thousands of times more precise and speedy.

HP sells a smartphone app that mimics the 12C.
Some of us need the dimensions and buttons of the real thing.
(In business negotiations where opening a laptop signals non-executive status, it's acceptable to pull out the 12C from one's coat pocket and punch in a few numbers.)

When the 12C batteries wore out after 15 years, there was no question that I would buy new ones. The calculator will still be in use over the next decade, long after today's computers have been scrapped.
