But the 15c 'Collector's Edition' had some issues, and I wonder about the build quality and reliability of this new one, too. Plus: my guess is you can get an original working 16c on eBay for less than this is going to cost.
Honestly, it pains me to say it but I'd recommend a SwissMicros DM16L instead: https://www.swissmicros.com/product/dm16l
I logged on for the first time in a while to actually talk about nerd things. God I loved the 80s-2000.
I have a 50g that I haven't used extensively, and a DM42n here on my desk at work (which I still don't use extensively, but aspire to).
I bought a 15C in the 1980s, and have enjoyed it ever since. It is like a rock. Despite being treated roughly over the years, nothing is wrong with it apart from some dents in the metal parts and my name, scratched on the back. I suppose I've replaced the batteries a couple of times, but that's it. This thing just refuses to die.
The main thing is that the keys still work like on day 1. And I've never seen a calculator with keys like this, with such feedback that you never need to worry about double-presses or missed-presses.
I just love the thing. If it died, I'd buy one of these new versions in a flash. But I think it will outlast me!
This is also the thing I'm most suspicious of with all these retro remakes - it's the physical hardware aspects that get screwed up so often.
If they get this right it would be legitimately surprising.
If you replace the batteries, get the good Panasonic silver cells from Newark, not "compatible" alkaline cells. The silver cells were intact after two decades.
Still nice to see, though the SwissMicros calculators are also very good and will be tough to compete with.
If this would be a 42, I would definetely buy it. My 42 is a gift from my father and time did not only good to it.
/edit switched UPN to RPN, as I got the translation wrong
The beauty of an RPN calculator was that nobody asked to borrow it.

(These days it's stored safely away with batteries removed, so I don't use it that much anymore. For convenience, I usually just use either Droid48 on my phone, or Emacs Calc at my computers.)
In high school it was mind blowing.
But I didn't do anything serious with programming. Normal languages seemed annoying, usr/rpl useless limited as it was to a 4 bit calculator.
Maybe if someone had told me usr/rpl is just lisp. But, it's for the best. I loath computer screens today.
(Edited) Actually it's not so much the door but the housing.
Learned a lot of RPN programming on those things!
I saw one in the wild a couple months back but had to say it didn't live up to my memories. Super slow and clunky interfaces compared to our modern touch screens.
The specific ergonomic feel of those buttons remains unrivaled.

Obviously it does not have the tactile feedback of the original. But it’s a far cry from using on a desktop with a mouse.
Using a REPL as a replacement does not mimic the experience, I don’t think. Not for me at least.
Mind, I’m talking a generic REPL. Like a CL REPL or similar, obviously not some custom calculator REPL.
First off, you’re missing the stack, which is significant. CL can almost mimic this with , *, and *. But while it provides a free, handy value store, it’s not the same. You’d end up with contrivances like:
(* * **)
So, for me, a calculator and its hand held form factor, especially something like the high end HPs, go hand in hand.
No doubt someone could (and likely has) code up a dedicated calculating experience, but a generic REPL I find to be unsuccessful in that role.
I still remember the way the buttons made a nice tactile thunk as you pushed them.
I doubt there are competent and cost-effective engineering teams in existence who could exactly match HP's numeric libraries in a $150 calculator that's guaranteed to sell a tiny number of units.
I do still have a mint HP48GX but never use it for the same reason. The successor the 49 had normal math as an option but it was not as iconic.
RPN but also something like Gnome doesn't match. So I use things like KDE that have huge amounts of configurability. I also deeply hate processes and methodologies at work and I often ignore them leading to endless stress for my more bureaucratic coworkers :)
TL;DR, me not liking RPN doesn't mean I think it's bad. It's just not for me and that is more a 'me' thing than an RPN thing.
Personally I'm not very flexible in that way, I want my tools to adjust to me not the other way around.
