What would your ideal HP calc look like now?

[Voldemar]

I think, HP 35s would be an ideal calculator. If...
1. It must be bugfree.
2. It would be with four or five line display (for entire stack).
3. There would be possible creat programm names with more than one character.
4. Matrix calculations (five line display).
5. There would be some keyboard layout improvements.
6. It would be with better hardwere quality.
7. It must be truly RPN calculator (no algebraic input mode).
For me (I am structural engineer) ideal calculator is RPN scientific programmable calculator (very good programming options). Ideal keyboard for me is when sin, cos, tg, x^2, y^x, square root, n-root, 1/x, log, ln, 10^x, e^x are not shifted. In addition x^3 and x^4 are not shifted, special for me :-).
