The Prime is fast and powerful, but IMHO not as well suited to interactive exploratory problem solving compared to RPN and RPL calculators. Ironically, if no more RPN calculators are made, the only options will be our laptops, tablets and smartphones.

It's true that it seems to be student-focused. I took the only available example but I don't own it and it wouldn't be my first choice in "recent" calculators. To be honest I'm not taking my HP at work, most of the time I'm using a calculator app on my desktop or laptop - RPN of course.

The HP-15C has the size in its favour, and they didn't sacrifice the access to the functions to achieve that, I mean you don't have to access everything through menus. But for me the HP-48 is easier to use, with its unlimited stack, clear matrix operations and readable programs. That series would be my first choice today for student or professional use, but I don't know if others feel the same, maybe it's just personal preference (and the HP-15 isn't far behind). Anyway I'm not convinced they'd make another one of those either.
