So I go back to my original question ....Why would I buy one instead of the other? (if they both existed today i.e. a DM42 and a DM43)
Summary of answers so far:

There IS NO DM43.

The WP43s does not yet exist, so it cannot be purchased yet (https://sourceforge.net/projects/wp43s/)

The WP43s is probably many years away from existing.

The DM42 exists now, so you have two choices. Buy a DM42 now, or wait for the WP43s to exist, which could take many years, if ever.

Or, of course, the third choice; wait for the DM43, which doesn't exist, hasn't ever existed, hasn't been mentioned as ever possibly existing and hasn't been discussed by Walter or Pauli (the W and P in WP43s).

I suspect you're getting mixed up between the WP34s and the WP43s.
My complete bad, I was indeed !!. :shock: :lol: Sorry - I wasn't trying to irritate you intentionally Keith. :oops:

I didn't even spot there were two WP models until just now :shock: , one existing (wp34) and one in the possible pipeline.(wp43)

No damage done, we're all friends here.

Take a look at the WP 43S feature list on the project page, it should be more powerful than the DM42, but also may be more complex to use.

I'm not sure the WP 43S will bring anything that will justify buying one for me . I mean I have already a 41CL, a DM42 and a WP 34S, so plenty of RPN power but when I want to do some quick programming or math exploration I just pull the Prime which is way more powerful and easier to program. I still like RPN programming as it was the first programming language I learned but nowadays I'm using it just for programming challenges.
And for calculations on the go a 32SII is perfect.

Even better: there are two existing (WP34S & WP31S) already and one (WP43S) in the existing (!) pipeline. ;) Just FYI.

Step 1 - Download Free42 on the device of your choice, play with it, learn its capabilities and decide if it’s worth paying money for either an HP42s or DM42.

Step 2 - If the answer in Step 1 is Yes, then save up your currency of choice and purchase a physical calculator from either the vintage calculator market or SwissMicros.

FWIW, I own a DM42, HP42s and WP34s (HP30b), and they all contribute to my enjoyment of RPN programmable calculators. The WP34s is a very different animal from the HP42s/DM42.

The obvious answer here, and I'm surprised no one has posted it yet, is get both.

The DM42 is available now and a wonderful machine, with pretty much universal praise. Even if you've never owned an HP-42S, if you know/like RPN, you will find it easy to learn and use, and in time with practice, even the advanced features (e.g. matrix, solver, complex numbers) are pretty easy to learn and use.

The WP43S will contain a similar/familiar but distinctly different keystroke programming language, and similar precision (as the DM42S) but also more features such as additional statistic functions, likely more/better solvers, additional Math functions (many of which I don't understand), roughly similar PC data exchange capabilities, and more. If I were a marketing guy, I might call it a WP34S on steroids, but I'm not, so I won't, but that should complete the idea.

Best GUESS is the WP43S will not be available for 2-3 years, unless some talented developers appear with LOTS of free time very soon, but it will certainly be worth the long wait.

So, yeah, pick the best choice and get both; very unlikely you'll regret it.

As far as I'm concerns DM43 == WP43S. This is at a minimum two years from completion and very likely more than that.
