Just back from a reading session in my Kobo, and I sent this article to it of course :) (through Firefox/Pocket). I can even read in the swimming pool (it's water resistant), nothing better than reading in sunglasses halfway in on a sunny day, awesome!!! And it doesn't weigh as much as some books. While I still prefer paper for certain reads, it has definitely helped get back into the habit of reading real books/reading more, so lost to smartphones and social media / "sugar" information type content these days. So convenient in terms of size/weight/number of books you can carry, while being easy on the eyes. No distracting crap, either, as TFA mentions.
Long live e-ink, whatever device you like most!!
