HP Prime too complicated

Entering the matrix and command in the calculator is even in this simple example much larger than 0s. Especially if negative numbers are entered.

And the complexity of entering data is one of the main problems when using any higher functionality with calculators. I would point that as one of the main reasons why I personally never bought a CAS capable calculator and why personally prefer simple scientific calculator (10-15x cheaper). It seems to me much more reasonable to use a laptop, tablet or a desktop computer with a proper software in a company for more complex calculations.

For a student, during exams higher functionality is most certainly deactivated or CAS capable calculator forbidden, according to "Calculator policy", thus it is certainly not a benefit to rely on it (if not explicitly requested).
