Rpl for the prime

[Michael Kathke]

It would be so great to have a full HP48..50g UI/stack/RPL on the HP Prime. My Prime is a dust collector. I tried it so many times but with my 48SX or my 50g I am always faster. The best feature on a calculator ever is/was RPL "on the go". RPL gives you a efficient way to automate or enhance calcultions on the fly. Having ALL features in one place (shell, stack) is the killer feature of the old HP RPL calculator series. Like Wolfram Alpha or Maple.
For me the App concept is the wrong direction. It is so limited because of it's closed environment. You can do what the App offers you but not more. And after all you need copy and paste between them...

This month I has to bought my son the first programmable calculator for school. TI-nspire CX without CAS was the model we had to choose. Here in germany, as far as I know, teacher prefer TI-nspire.
Against my expectations I was very impressed. Even for me as a very intense HP user since 48SX the first contact to the TI-nspire CX is more intuitive than my Prime. Even without reading any manuals from the TI. I only prefere the prime touch and screen over the TI mouse pointer. But working within the calculating area, with apps, the menues, the PC/Mac App etc. It is so much more advanced on the TI side.

In my opinion HP tried to copy TI. And they build a great hardware (beside the unreadable orange on white keyprint) but lack in the overall usability concept. They have a long way to go with the Prime concept. TI is years ahead.

@HP: And for me as an EE? I dream of a modern 100% stack based, full featured RPL calculator. HP50g functions with 48SX keyboard usability, Prime display, memory and CPU power, SD Card...
