Per my own usage, I only prefer to use the e-ink monitor for long reading/writing sessions. For writing, I use the customized color scheme in this gist in Vim, and type along for hours. For reading, I use Calibre Viewer to read EPUB/mobi books (this viewer allows for batch-exporting the highlights and notes). I usually pull for such sessions when my eyes "burn" after using those "normal LCD monitors" for a prolonged period of time.
Compared to my "normal monitors", the e-ink monitor is simply too small. In portrait mode, I can fit at most 60 lines with comfortable font-size. In landscape mode, there are 35 lines or so. Since tuning the syntax highlighting can only do as much with the limited gray scale levels, I hardly find myself writing any code on the e-ink monitor. Even with the perfectly tuned colorscheme, my eyes can only tell a very limited amount of gray scales.
Dasung, the company that made the e-ink monitor in the screenshot, is selling a larger 25-inch e-ink monitor. I haven't been able to get my hands on it as it is currently only sold in China.
