What would you like to see in a future HP Prime II? (HP Prime², HP Prime 2X)

[acoto]

I will like to see a congruent family of calculators, same look and feel, but with a steep up path. All of them with default RPN entry mode. ( Not sure about wanting Algebraic as secondary option)

Will like to see a
- Basic RPN 4-10 function calculator, 4+ line display, large stack, illuminated.
- Intermediate RPN scientific,
- Advanced RPN scientific,
- Full blown engineering RPN, programmable, CAS, statistics, financial

And in a parallel universe
- Intermediate Financial, RPN
- Advanced Financial, RPN

I will like 7-8 year children to start with RPN thinking, and evolve from there.
