I have a Dasung e-ink monitor (by the power of grayscale). I find a lot of interesting reading on my work computer, but getting those links onto e-ink devices like my Boox has been irksome. Reading on the e-ink monitor was _almost_ worth the price. Ultimately, however, I retired it because the desktop real-estate, macOS's limited multi-monitor capabilities, and if I'm going to buckle down and read something long form I need to get away from my desk anyway.
