Imho, 50g and Prime are different beasts.
I am a chemical engineer and used a 48 series calculator since the university (more of 30 year ago).
A couple of years ago i tried to use the Prime (virtual) for daily work and simply failed.
Even considering the bias of being a 30 and more years 48/50 user, i found thant the Prime lacks several features i need: UOM (conversion/usability in solver and calculations), an omogenous approach to several data type, RPL/RPN, only one environment for any kind of possible use.

So, after my experience, imho the Prime is not aimed to engineering professionals and that's why the 50G (and even the 48g+/gx) price is sometimes higher than Prime's.
