It gives me a chance to talk about the wander, mystery and efficiency of post-fix notation and all the many reasons it's superior.

yeah that can be amusing, unfortunately very few were at all intrigued by the 35s in my class. People here go through every school stage being told exactly which calculator to buy, and sometimes the teacher even make the purchase for them. So i guess the relation with these devices tends to be utilitarian and joyless. up to 25 people using the exact same casio make the calculator a thing that you just fish out of your backpack and not a faithful companion through school and uni. No body bothers marking their casios, these get switched around like crazy, my hp 20s is the black sheep, the teacher calls it "der Gurkenrechner" alluding to its age, everyone knows who it belongs to. even the deriding nickname is better than the no name casios : )
