Can we have RPN back?

[Craig Thomas]

The reason I'm not using my Prime as an engineering calculator is simple.

x to the y key

and

nth root of x key

Currently, in Prime RPN, these require entry backwards compared to my other 5 HP calculators and it's way too easy for me to make errors because of this. I'm happy to clarify this if anyone want's it.

The transition between all my older HP's and the HP48 (my last new HP) was seamless for me so I'm perfectly happy with a limitless stack and I rarely program; I'm not sure why talking about RPN is tied to a 4 level stack only, in comments here, and is suggested as a reason to not 'do' RPN in a 'classic' way.

Perhaps I'll trip over other inconsistencies but having set my Prime aside for now, I'm not finding them.

Anybody who has an 'old' HP (up to the HP48 series) would be pleased to consider the Prime as an update except for the error generating keys I mention above...and the keyboard colors.

This might make it clearer:

If I could buy an HP-21 with a backlit screen and lithium ion battery, I'd buy 4...up to $75 apiece or so.
