I like (although I not always prefer) reading physical books. After losing my previous e-reader, I got a second-hand Kobo Glo HD. It's an old model, but almost everything works as intended (not really for the wi-fi connectivity, due to some SSL certificate shenanigans, and there is no red-tinted backlight). I've been reading digitally for many years, now, and it's my preferred medium for tackling non-fiction.

Digital books (e-books) are sort of the intermediate step between paper and the internet; it has allowed for some nice things. Some people are wary, though.
