WP-32S in 2016?

what for do you want BT (when you've got USB and SD)?
Communication between units and share your data/equation/program or full backup to your phone/tablet.
Sounds like belt and braces to me. And BT eats batteries.

backlight LCD without backlight function labels?
Backlight for keys also required and for the plate of keyboard (to see the 2nd functions)
Now we've lift-off, haven't we? Personally, I calculate at daylight. YMMV.

What statistical stuff do you miss?
For example I am an engineer and I have a model of a process (a diffeq). I want to make the solution with my calc and after than I want to fit the solution into my measured data.
If I have an equation of this model I can extract additional informations about my process (slope at any points (how the process is fast), integration of the curve (how many material/power consumption on this interval), etc...).

Two simple examples:
a.) try to fit your HP48nn calc a linear function which is crosses Y-axis at Y=1 or
b.) fit the quadratic function which have dY/dX=-1 slope at X=0

these additional features everyday requirements during engineering problem solving.

You did want a non-graphing calc. I do not recommend doing advanced curve fitting without some visual feedback. You may look at the numeric residuals though I'd prefer looking at the graph as long as possible. There may be situations where the numeric results tell you more about the goodness of fit but I'd think such applications are beyond the realm of a pocket calculator's micro screen. Again, YMMV.

I just want to understand...
I hope you're not an idea-grabber. You know that, I have lots of idea but I have no possibility to make them in reality. How many you want to pay for me these ideas?!
Csaba, I feed this forum with ideas (even drawn ones) for quite some years now and didn't get a monetary equivalent for that. In fact, all of us who post here do it for free. (The many folks who just browse and read these fora are much more dangerous for you and me, they are the exploiters.) I'm afraid you will have to share our (non-) pay or fall silent.

A function set of an HP-48GX crammed on the surface of a Pioneer seems a bit unrealistic.
No need. Use Categorized Catalog (Real/Vector/Matrix/DiffEq/Solver functions) and Customized one also.
That exceeds my understanding. Please elaborate if you want to.

You'll need softkeys at least, meaning a larger LCD than the Pioneers had.
Hmm, maybe. It needs to decide which one is better (softkeys & menu or one line only)
As above.
