It is marketed as a pupil's (or student's) device, who are to learn mathematics or physics.

But in the time they need to learn how to use such a calculator including CAS, graphics, programming, they better learn mathematics itself.

My daughter (13 years old, she likes mathematics) didn't even look at her calculator's manual, she simply isn't interested.

Personally I'm glad her school recommends the Casio fx-991, a non-CAS, non-graphics & non-programming calculator that cost us less then 20 €, and is IMHO more powerful and complicated than is needed.

You are comparing a €20 calculator for middle school against a >€120 top-of-the-line calculator for university/engineering workloads and complaining that the latter is way overkill for your 13 years old daughter whereas the former does the job just as well. That's like comparing a SS-520 rocket with a Space Shuttle and complaining that the latter takes $1,500,000,000 to deliver a 1kg payload to orbit while the former only takes $500,000 and does the job just as well.
