Calculator Wars at your School

[cesarb94]

I'm interested in knowing what were the groups that fought each other arguing which had the best calculator at your school and also at which time frame.

For me, in my bachelor in Mech. Eng. It was the HP50g/48g vs. the Casio FX82-MS. The Casio guys argued that using a Graphing calculator was too easy, and they were the real engineers. Never seen anyone with a TI calculator there. Meanwhile me and the Heat Transfer prof were the only ones with a 35s.

This was from 2011 to 2017, at my uni in Brazil. Now in my masters, everyone uses the 50g.

What about at your location?
