Overall I think the fx-991CW is nice but I don't understand why Casio does still not have a persistent calculation history. That has been a pretty standard feature for decades with competing scientific calculators, right?

It's mostly because they design their calculators to suit exam/school requirements, and leave out a lot of useful features that would get them banned.
