> I’ve noticed that most physical scientific and graphing calculators are easily outdone in terms of performance, capability and ease of use by the likes of Desmos and the default calculators on OS’es like the iOS, Android, and Windows.

Citation needed. They are pretty clunky, unless you have a numpad typing on them takes way longer. Graphing and fast access to mathematical functions is way worse.

I mean I do substituted my calculator with the computer, but the replacement is Python and GeoGebra, not the built in calculator. And the reason is mostly convenience of not replacing batteries. I do use the standalone calculator while the batteries are full.
