Or did you mean a portable calculator that you can use in a place like a library when you don't want to carry your laptop ? If you meant the former, then I just cannot imagine someone having time to focus on the lecture and then busy himself playing with their calculator. How does anyone have the time ? In fact, since I left school, I don't even take notes in class anymore. I just sit down, listen, jot down a few keywords, and that's it.

Actually both. Here in Brasil we have a different approach to teaching engineering at university. The courses are five years full time, and the classes are less like lectures. You are expected to solve problems during class in many cases. In the last two years you even need a graphing calculator to do the tests, otherwise good luck finding eigenvalues or inverting a high order system.

I did a Control Engineering exam based on State Space approach and controller design and not even a pocket calculator was allowed. We had to invert and find the eigenvalues/vectors by hand. Granted, none of the matrices were more than 3x3, but what's the point of asking anyone to do a 4x4 matrix ? In fact, calculators are not allowed in most exams here (Germany).
