Paper is fine if you're the kind of reader who can get a couple of weeks out of a book. When - as I'm guessing most of us on here are - you're a "books per week" reader, paper gets inconvenient. Especially on a longer trip to a non-english speaking country where the local selection is limited.
I used to take half a dozen on holiday with me, now it's just my Kindle.
