I have a Dasung monitor (black & white, not colour) and its reasonably good for coding. You need to use light themes on eink devices (I use the default Emacs theme), as using a dark theme does lead to unusable bad ghosting.

Mine is a few years old and newer panels are better, so I would expect this to be pretty good.

I do! I mostly use JetBrains stuff and Sublime Text. The ghosting is a non-issue for me.

I do keep a color calibrated panel running next to it in case I need a video going or something (conference, etc.). But the ghosting is a non-issue for coding once you figure out the settings and limits that work for you.

Of note I spent a chunk of my career working with and programming on a Harris H100 via terminal, and slowing down is a nice little throwback to me.

same! I am curious to know this as well.
