I remember the time when it was "reading books on something without paper and ink is goofy in the first place". :)

I gave up on e-ink readers a few years ago and donated a couple of them. I am reading books in eletronic format on iPhones. It's just more practical, I don't need to carry a second and usually larger device with me, and ... I don't need an external light when it's too dark to read. Plus, the newer iPhones with OLED displays are pretty good for reading.
