Battery backed non-volatile memory is also full, something will need to be traded off before any more can be used.
We've pushed all the resources in this device to the full.

Thats one of the reasons why it became this product!
Taking all that into account, IMO the mathematical features of WP34C should remain always have higher priority than a possible UNDO or LastXY function, because in practice it is not so often used. To be honest, in my RPN history, I think I didn't use f LastX very often to correct mistyping, I used it sometimes in programs as an additional register, its just an old feature, that HP invented nearly from the beginning.
