The actuel Prime future...

[ww63]

The "bugs in prime" they are referring are the ones from the first firmware releases. Other dealers like dynatech.de still sell both calculators.

I think, the problem with the "lack of demand" is, that Schools here in germany mostly recommend TI or Casio. When I went to school HP calculators were much to expensive for general use in schools (there was the 41C a new product).
And many teachers and pupil didn't like the RPN.
