> I do the same thing with books.

Can relate, I go to a Cafe to read almost every morning, even if I'm just reading for 5-10 minutes.

I usually read 1-3 books in parallel because sometimes I'm just not in the mood for non-fiction and I just want to read a quick interview with an interesting person. One of the best features of ebook readers for me is that I can easily switch between books with a few taps, instead of having to bring 3 books.
