I totally agree with you.

I don't see why. It's a keystroke programmable. the programs are pretty much the same as the keystrokes you'd hit to solve the problem manually. Add some LBLs and GOTOs for looping and add a R/S for any place you'd like to enter a variable at run time. That's about it for a basic (not BASIC) program. Of course there are many other features but those are used if you want to make the program fancy. You already know how to calculate manually using RPN so writing a program in it should be a piece of cake (easy as pie)

It is not a matter of how to write a program or RPN vs RPL (i also use a 35s, sometimes).
It's more a matter of being used to the unmatched flexibility of RPL object oriented approach.
I use my 48gx and 50g for everyday calculation and to write programs and utilities related to my job.
Disclaimer: All the below is totally IMHO
The solver(s) are parsec beyond HP42s/DM42
The object oriented model allows user to handle nearly any object in a coherent way
The availability of data type like list let to me write very complex programs quite easily.
Not to mention the outstanding uom handling and the capability to organize memory using directories
... And more....

That's why i feel the DM42 and even the future WP43 (whatever will be its final name) too limited to replace the 48/50 on my desk and too expensive to replace my 35s, which I use lesser and lesser.

RE: Top three calculators ?
I agree with a lot of what you wrote. I love RPL because it is aligned with the way I write software generally. I like to build foundation pieces and build something on top of those. In practice, RPL is difficult and mistakes are very costly. I don't love it until something is perfect, but I still like it a lot more than keystroke programmables and it is certainly much more powerful for code I want to keep around forever.

That said, keystroke programmables really shine for one-off jobs. There is no stack-dancing, no hair-pulling and no groaning when you make a mistake. It's really easy to fix errors. I find I might write a keystroke program for a quick job where I wouldn't take the time to write it in RPL.

I don't have a DM42 or an HP 42S and I'm not really interested in either. If I had an HP 42S I probably would buy a DM42 and I still might some day just to have one. But I wish Swissmicros would just put out their 41L in the correct portrait format. That would be pretty much icing on the cake.

It ain't OVER 'till it's 2 PICK

As a matter of fact it is possible to program a RPL calculator in a way similar to keystroke.
Just type << and start pressing the keys you need :-)

RE: Top three calculators ?
At Work:

1) HP 50G (HPGCC and USER RPL programming, unit conversion)
2) HP 15C LE (quick calc + unit conversion too)
3) HP 48GX

At home but still related to work:

1) HP 75D (quick programming)
2) HP 71B (quick programming and calc with HP41 PAC)
3) HP 49G+ with last generation keyboard (quick calc HPGCC and USER RPL programming, unit conversion)

In my bag, at home, at work, when I am travelling:
HP 200LX (lotus 123, gnuplot, derive, vim, matlab, awk, basic and Fortran with open watcom compiler)

It's good to see someone else giving the 33C some love. It's a great little calculator. It feels so robust in your hand.

RE: Top three calculators ?
My top 3 calculators:

1. DM 42 - not a HP sure, but this just does EVERYTHING - I've invested lots of time into programming this
2. HP 41CV - my goto calculator before I got the DM42
3. HP 33C - It's like a HP25 shagged a tank! This thing just inspires confidence it feels so rigid in the hand. And I've always loved the slightly larger LED display.
