I think this tradeoff was to keep it compatible with Collegeboard's (archaic) calculator policies, which forbid keyboards. [1] Being able to market the calculator as SAT-approved is probably super valuable since most students won't buy multiple calculators.

It'd be pretty tough to use it on the SAT if you take most of the allotted time trying to type out a function.

While you're right about how long it takes to type a function on a calculator like this, this calculator is a huge step up from the TIs kids use on the SAT right now.

That's valid.

You can use it just like a TI-84, its just that it uses Python (which programming curriculums in k-12 are increasingly using) instead of TI-Basic.
