Ebook Milestone

Amazon report that for the first time, sales of eBooks (for the Kindle -which presumably could include sales to people with iPads using the kindle app) exceeded hardback book sales.
This sugests to me that eBooks could be about to become disruptive; and will certainly start making inroads in the academic book market. When my daughter went to University last autumn we bought her a macbook, and she has told me that she does use etexts on that, but she is still a very heavy consumer of conventional books. Should her brother go to university in three years time, I now believe that an eReader will be part of his kit, but whether as a dedicated device or something he does with his lap top is not clear.
