Be aware that Boox runs Android apps. Many other brands do not.

I use the Boox 10.3 for reading emails, text-based sites like this, and manga. Its bliss and has replaced 80% of my ipad. The experience of using it outside completely trounces normal screens.

As soon as they make larger, better 60hz panels I will 100% switch all my monitors over. I think making videos look worse is a positive. We don't need doomscrolling. We don't need 60fps react buttons with smooth gradients. We don't need to HDR the entire web. I primarily use text based sites anyways, so eink is perfect for me.
