Org mode on remarkable2 would have me there in seconds, especially if pen input to org mode worked right.
Or maybe onyx boox?

Avoid Onyx Boox, they explicitly refused to honor the GPL. https://old.reddit.com/r/Onyx_Boox/comments/hsn7kx/onyx_usin...
If you're looking for non-RM alternatives, I'd start by evaluating (I haven't) the Quirklogic Papyr.
Personally, I don't think the RM is a good long-term partner for the Free Software community - half the reason the modding community exists is because the RM team refuses to provide some basic features in the name of "simplicity". They'll never want to support a wide variety of use-cases, they want to be like Apple. I imagine the solution here is making an RM-specific distro (and community explicitly segmented from the "RM OS with mods" community), adding support for other ewriters, then deemphasizing the RM.
Outside the remarkable and a few locked in reader only tablets, the market gets really sketchy (no pun intended) real fast. Lots of questionable companies and brands like Boox, which is disappointing as feature wise the Boox hardware seems more ideal and hackable than the comparatively (and intentionally!) primitive/restricted remarkable kit.
There are a few sort of decent companies with okay products, some even publish their modded kernel sources, but in the end I've never been able to pull the trigger on these $300+ devices that often have both severe hardware and software limitations.
eInk is cool, but it's hard to toss that kind of cash around with so many strings attached...
The onyx boox have bluetooth and you can connect as keyboard to it and since they have access to the play store you could probably also run vim on it. This is something I miss on the rm2.
