What models use "HP-48 style" enter?

I'm wondering more from a UX perspective whether there was a motivation for it

I know some people have strong feelings about it too, so even of the behavior is effectively a side effect of using RPL, it has UX implications as a feature on its own (and presumably could easily have been implemented either way regardless of RPN vs RPL).

So that's really my question: what were considered the "styles" and "audiences" targeted by each behavior for ENTER.
