Actually, when someone is only posting to say "Ha! this CAS does not even simplify this properly" or "this CAS does not return the expected result for that", etc. and pretend he knows better than me how to code CAS software because he wrote some symbolic code in the past, shoud I react by asking "Great, send me more?"

Obviously, yes! ;-) :-D

The thing is that CAS systems are different.
It is possible to go on different routes, for example:
A) Develop a CAS with High School and university first year math
"usual" answers (I call this Fake CAS)
B) Develop a CAS that unusable for the poor undergraduate student
with no Thesis in CAS building
thus making the CAS unusable to anyone else except for specialists
C) Balanced CAS - somewhere in between the extremes

The main problem is that you can't please everyone.
One solution would be a specific CAS settings application - if HP likes the idea -
where all these requests would be gathered along with additions to the [Help].
Who pays for this? Who has the time to develop, test, and maintain it?
Will it bring HP an advantage in the market?
Without it would HP Prime be consider somewhat inferior to, say,
TI-Nspire CX CAS (which I also own both in a PC and physically)

I think HP should be superior in every way
and since many people here point out errors/incompleteness/different behavior
they still should be taken as a positive feedback and considered seriously.

Not every (old) High School teacher have the capability to explain CAS quirks to students, therefore I strongly recommend you consider adding
for the user (teacher/student) to optionally "stupefy" your CAS
even if you thing that for higher math the result is wrong.

On the other hand this would IMHO require feedback from the educators in France.
How to make Giac, KhiCAS, GeoGebra, HP Prime CAS, more user friendly?
I'm again talking about high school level math (or first year university).

What about HP? Tim Wessman?
