Glowing in the dark is as much a bug as a feature. Lit screens work best in a dark room, where a reading light is more pleasant when you pause reading to do something else.

I spend an inordinate amount of time either turning lights on an off or trying to use the not quite sufficient tablet screen to do stuff.

An e-ink reader does it better because the front lighting is less glaring and the overall image is more stable. It’s hard to get a phone screen to the right brightness level for reading in the dark, but an ereader will have a very dim front light that you only notice when the room is completely dark.
