I heard a discussion on Radio 4 this week about the relative merits of ebooks vs physical books. The upshot of the debate seemed to be that, despite publishers' initial wariness, people were beginning to impulse-buy more books than ever before, due to the always available ebook-stores. Certainly, people seem to be buying much more than they read and, as there are no bulging shelves to show for it, it's very easy to do.
However, the radio conversation went on to suggest that people are purchasing ebooks to decide whether they like a book and, if after they have read it they have enjoyed it, they then trek out to the local bookshop and buy a physical copy... in effect, buying the same book twice. I'm sorry but I just don't believe that.
