Quirks: Expect ghosting. You'll have to press the "clear" button if the only thing moving on the screen is the mouse. This is oddly satisfying and not nearly as annoying as it sounds. Like "time for a fresh slate!" Getting the right contrast is also something you'll have to get used to. Dark themes are basically unusable because of ghosting. The monitor's very high DPI isn't handled well by gnome, so stuff is smaller on the eink display than on my main monitor. It's got different needs than an LCD in terms of software configuration of themes, color management, etc. I don't think any OS was made with this thing in mind, so there are quirks. I wish there were some better "per-display" settings in gnome. But oh well.
In spite of the quirks, I don't regret getting this thing at all. It was expensive but now I'll be able to work outside. It's way easier on my eyes.
Right now I pretty much just use it for reading and writing code or doing stuff in the shell. And it's great for that. Vim is like the perfect text editor for this. I also got vs code setup alright for it too now, but it's really great with vim, and has been motivating me to use vim more.
Btw, I also got the Dasung "not e-reader" tablet which is also awesome.
These devices are quirky but really well made and designed.
