How's the page turning speed and/or screen refresh speed? I remember looking at an e-ink reader years ago and thought it was unusable because of the weird page

  They've generally gotten faster over time. The newer ones also have partial refresh modes that are faster still, but not quite as clean, which lets you trade speed for clarity. The fastest modes work for video (sort of) and at least the Boox have lots of configuration options e.g. different apps can refresh at different speeds, the refresh rate can vary when you start scrolling (in standard android apps that aren't optimised for e-ink, in readers you generally "page" through text) and can set it to do full refreshes after X amount of actions, or manually force a refresh. But, as all the above probably indicates, if you have it on full quality mode, then there's a noticeable delay and flicker as it fully blacks out the screen to "clear" it and then displays the next page. This is particularly bad for some of the color ones, as they seem to only be able to do each color layer in sequence.
