The hp-prime is very complicated because the development group has not been able to unify the numerical mode (HOME) with the symbolic mode (CAS). I propose solutions but they have not been taken into account, such as:

The researchers in mathematical education affirm that from the primary level algebra must be taught, since algebra is the area of mathematics that is used in almost all other branches of mathematics (see godino) http://www.ugr.es/~jgodino/ this implies that if the teacher wants to incorporate calculators in the classroom, it should be with calculators with CAS and not only numerical calculators, simple calculators like CASIO, NUMWORKS that do not incorporate CAS are not suitable for teaching- learning of current mathematics, but calculators with CAS should be used to improve algebraic reasoning, not to return results. There are still no teachers who are trained to incorporate the technology of calculators with CAS in the classroom.

The hp-prime CAS is not only used for the primary and secondary levels, but also tertiary (university)

I agree with you that algebra is very very important.

But I think algebra should be learned "by hand", with paper and pencil, so pupils will get a deeper knowledge. -> no CAS needed.

Concerning university:

In exams you often are not allowed to use programmable calculators -> no Prime.

In other situations (homework etc) when you need a CAS (or advanced statistics or programming) you easily can use a PC.
