You may well be right, but I couldn't say myself. I didn't get it from U2 by U2, I don't think I owned a copy back when I changed it. I only had my old one for a couple of months before changing to this thing.
I have one hardback copy and one paperback as well. I have only read the hardback one, but I carry the paperback when I travel (easier to carry around just in case I stumble upon one or various of its writers, you know )
