Addressing a few points that have been raised about e-ink, apps, and Android, I've been using an e-ink tablet as my daily driver for the past three years (Onyx BOOX Max Lumi, running Android 11), and have a pretty good idea of the capabilities and limitations. Overall, the device has been far superior to any earlier Android device I've owned for overall readability, usability, battery life, and satisfaction. For a demonstration of what e-ink displays are capable of, see this video, which starts basic (static signage systems), and progresses through video-capable displays (not, it's true, high quality, but serviceable): <https://yewtu.be/watch?v=KdrMjnYAap4 https://yewtu.be/watch?v=KdrMjnYAap4> An Onyx BOOX Note displaying video, similar to my own device: <https://yewtu.be/watch?v=XRDJv_-wWBI https://yewtu.be/watch?v=XRDJv_-wWBI>. For e-ink tablets and mobile devices there are typically multiple display modes, which can be set on both a per-app and overall system basis. It's reasonably easy to switch between these where needed (e.g., on a Web browser). Higher-quality rendering comes with slower refresh, and there's a trade-off for visual quality vs. speed, but even basic animation is possible with only very modest quality degradation. "X-mode" for full video sacrifices a lot of quality, but you'd typically use that only for video-intensive apps (or occasional video viewing in a Web browser). The main side-effect is ghosting at higher refresh speeds. Android devices can use third-party app stores such as F-Droid (VERY strongly recommended), with an independent selection of apps, or the Aurora Store alternative interface to Google Play Store which provides any Android app available through Google Play. I minimise the apps I've installed, and have avoided virtually all authenticated services (one article-managing app excepted), to minimise distractions, but have several installed from both sources. E-ink itself does have its strengths and weaknesses. I like to say: Persistence is free; pixels are cheap; paints are expensive; refreshes are slow (1-8 Hz rather than 60--120); shades and colours are limited or nonexistent; line-art, dithered images, and half tones render quite well (raster and gradients far less so); paginated navigation is vastly better than scrolling; graphics are reflective rather than emissive; touch/Wacom may exist; and feature-detection capabilities are limited (e.g., CSS @media queries). It's a different medium, and rewards some adaptation of design principles. See: <https://diaspora.glasswings.com/posts/638a8d10e041013afba8448a5b29e257 https://diaspora.glasswings.com/posts/638a8d10e041013afba844...>. I'd make one further addition: dark-on-light styles are hugely preferable to "dark-mode" (light-on-dark), which is far more difficult to read. Generally, e-ink prefers full black on full white styling. I'll note that apps which are designed for e-ink, most particularly EinkBro (an adaptation of the FOSS Browser) make for a much superior experience: <https://github.com/plateaukao/einkbro https://github.com/plateaukao/einkbro>. And yes, there are full e-ink monitors which are available for desktop systems: <https://shop.boox.com/products/mira https://shop.boox.com/products/mira>
