I saved my pennies and bought a TI SR-52 in High School. A friend had the HP programmable equivalent. I never could get the hang of RPN, even though it was supposed to be “faster” with fewer keystrokes.

TI vs. HP set the stage for a whole lot of other "Holy Wars" that followed in the dawn of the tech era: vi vs. emacs, big vs. little endian, BSD vs. AT&T Unix and more. Since I had Lisp programming language background, RPN came easier to me so I had to slow down and think a bit when I had to deal with the TI notation.

I have a vague memory of seeing ads for HP calculators that let you choose infix or RPN. But once I was actually a professional and had the coolness of an actual computer at my fingertips with a real live 24x80 screen and QWERTY keyboard, I never looked back. My old calculators just gathered dust and battery leaks, never to glow their numerals again.

“TI vs. HP set the stage for a whole lot of other “Holy Wars” that followed in the dawn of the tech era: vi vs. emacs...”

There was no holy war with Vi vs. Emacs.

How could Vi compete with something so superior?
