What has the DM41 extra over the HP42s?

[Dave Britten]

I've only been seriously using the 42S and DM42 since around 2017, and it's typically my go-to calculator when I'm not doing work that's better served by a more application-specific model (e.g. financial calculator, programmer's calculator). So it's certainly not nostalgia in my case.

I also have a 41CX and DM41X, which are terrific machines, but the 42 will have undeniably broader appeal to someone not entrenched in the 41 ecosystem (or who just likes tinkering with old computer equipment).
