I have long been a fan of Casio. I love the easy to use interface. Math functions that stay accessible for problem after problem without having to start the menu process from the beginning each time. Intuitive graph solutions (no right-bound, left-bound for intersections) that includes x and y calculations. The ability to graph a line of best of fit for additional calculations.
For many years, I was on the hunt for the 'perfect' calculator that had MathIO and included graphing, matrices, and stats, all for an affordable price. This calculator has all that and more. I teach HS mathematics. Once I show students how easy it is to use, they want the Casio over the much-hyped and over-priced TI-84. My fellow teachers are more comfortable with the TI but they also have to spend class time teaching how to use it. Sure, sometimes I need a refresher, but the menu aspect of the Casio is faster to navigate through.
When this pandemic is over and I have more time (in theory), I want to explore the Python programming option more.
