This is the copy I've been carrying around with me for the last couple of weeks, with the receipt I've been using as a book mark. It's an 800-plus page book so I felt the usual sense of achievement that I was not merely getting through it but also enjoying it. I liked feeling it in my hand and putting it on the bedside table at night.
I've also bought myself a Kindle, which clearly has a place for anyone who does a lot of reading. But if I'd read "In Europe" entirely on the Kindle I would miss not being able to look at it. If you've invested this much time in something you like to be able to see it and touch it.
I'm the same with music. Downloads are fine if all you want to do is listen. But if you really appreciate something you want to own it.
