No, you was totally clear and I was not.

I think, always must to divide the users (the market):
a.) The students are not professional users and for students must to produce a "good but not professional" equipment - which are accepted on exams.
b.) The professional users (like engineers, scientists, etc...) do not selects "good but not professional" equipments - because they have experience and they can decide which calculator is perfect for him/her.

The real problem is that, no transition from a.) to b.)

A practicing engineer will be select a good calculator from 80's with solve and programmability, lots of memory.

The ideal engineering calculator: like 15C in 32S house with functions of 48GX and memory and backup capacity of 50G.
