Yes.

If you want, you can think of e-ink displays like this:

- Persistence is free. Once an image is set, it remains indefinitely. Even with no power applied. I've noticed no degradation over days or weeks, and expect images would be retained for years.

- Pixels are cheap. Dot densities are on the order of 220--300 dpi. This compares with many consumer-grade laserprinters. High-definition printers approach 600 dpi, photgraphic printers perhaps 1200 dpi. At a even less than a meter distance this is undetectable. I can just make out pixels under a high-power magnifying glass.

- Repaints are expensive. It is changing the display which costs power, not sustaining it.

- Quality/responsiveness is a trade-off. At maximum frame rates, displays achieve about 4--8 Hz (fps). Quality degrades considerably with ghosting and contrast issues. High image quality comes at low refresh rates (0.5 -- 2 Hz), but is at or near paper quality. Higher-quality repaints induce greater flicker, lower-quality, less.

- Colors and shades are few. Most e-ink displays have limited greyscale palettes, typically 4--16 shades. As a consequence, even B&W imagery appears posterised. For fine art other than line drawings, you'll want a dithering or halftoning pre-processor for best results.

- Overall contrast is also lower than a black ink on white paper. It's closer to a very dark grey on a somewhat off-white, though under bright light (sunlight or artificial) it is highly readable and pleasant. More so under sunlight than an unshaded paper which tends to be too bright.

- Frontlights enable low-light viewing, though they tend to reduce the darkness of blacks whilst lightening the whites. I prefer both ambient room light and the frontlight for indoor / night-time reading, though it's possible to read using just the frontlight, of course.

Displays are exceedingly well suited to text and line art. (The Onyx BOOX line comes with pen-and-ink line art for power-off and suspend screens, by default. These look delicioius.) Stark black-and-white content (say, Picasso's "Don Quixote") also render marvelously. For photographs, I prefer a halftoned render (this is achieved automatically at certain display quality settings on my device). Mixed-colour, low-contrast gradient images, especially nonphotographic images, seem to be the worst option. Anything which leans heavily on colour for context comes out quite muddy given both the B&W and limited greyscale pallettes. Website animations are immensely distracting as they result in a whole-display flicker at high disiplay quality, and a strobing effect of the image itself at modestly lower-quality rendering.

Navigation by pagination (where the entire page changes at once) is vastly preferable to scrolling. At high display quality, the latter just disolves the screen into static, making tracking of how much you've scrolled and where the new/old content division are difficult. Tools such as the EInkBro browser default to paginated navigation and make Web browsing very much better than a stock browser (say, Firefox/Chrome, or anything based on scroll). I find myself trying to invoke EInkBro's pagination on Firefox all the time.

(The BOOX is an Android-based device. It's a tablet that happens to be an excellent book-reader. I've been using one since March.)
