Why are the HP Prime and HP-35s so unpopular?

[Artur - Brasil]

I had the Prime for about 1 month - the latest model. Very fast, very powerfull, but, when I tryed to make some units calculation it was my first big disappointment.
So, it came programing: a new verbose language, like Pascal; in the caculators keyboard, forget it; so, you must use a computer - but, if I wish a computer, I should had bought one, not a calculator;
Third, the fault of directories... just my preferences.
Fourth - two calculators in one: the RPN system and CAS system - the great range of objects in HP-50G had gone...

So, after all, my 50G is doing so well in my EE course, with Laplace transforms, etc (and for other simple math, my 41 is so good), I just step back and sold it.

Indeed a beautifull new computer companion calculator.
