You could give me a Casio for free and I still wouldn't use it.

Why not? It's an excellent toy for exploring mathematical concepts.

Excellent? They've literally been sued over their inconsistent and poor programming. You can type a simple arithmetic expression into 2 Casios and get 2 different answers. Half of their calculators fail to follow basic order of operations. There's nothing excellent about them. There's a reason the vast majority of schools recommend, or outright require, TIs
