In fact, Chapter 14 of the HP 33s user's guide is word for word identical to Chapter 15 of the HP 35s User's Guide. It also didn't eat batteries, had direct rectangular<>polar coordinate conversions, and separate dedicated primary keys for STO and RCL.

True, the 33S is a good calculator but it is so astounding ugly, I still cringe every time I pull it out of its case :/
