Calculator Wars at your School

[born2laser]

In high school I must have been in the last class to learn the slide rule (and to use log tables to make calculations, hated that!).
I was the last in my class still using the slide rule, and was faster than anybody else using calculators, but had to give up when we started calculating structures, there are too many sums and the slide rule does not help there. I got a CASIO FX21, and I loved it (smuggled into Argentina, imports were closed at the time). My cousin had a FATE 10 calculator (built under license locally) that introduced me to RPN, but that calculator was a beast, 6 AA batteries and the red LED display just ate through them.
In college I had the opportunity to play with an HP33E, and again fell in love, now with programmables. By the time I could buy my own most people had TI58 and 59, but a dedicated minority (myself included) ponied up for the HP41
