Just an innocent question/suggestion---I know neither how its realization will affect the HP Prime marketing strategy and the HP 50g sales nor what resources it will bind:
Would it be interesting for HP to make those professionals happy with the HP Prime who do not need an IR or RS232 port and do not have to change SD cards (frequently) but like to make use of the amazing hardware and the "next-generation" programming and (expandable) visualization capabilities of the HP Prime beside the valued RPL within a 50g app?
I think, the I/O could be virtualized (files, USB port) and the 50g display could simply scaled by factor 2 (262 by 160 pixels (b/w---anti-aliased?) plus a border for status annunciators and softkeys for the missing parts of the 50g keyboard)...

Edit: Please excuse if there was already a thread treating this (maybe stupid) idea.
