I note with some amusement that Macworld have bought out a paper guide to the iPad. You cannot buy it as a download you have to buy a physical copy. Naturally the sampler is in pdf. I guess until the publishers see the medium as a relevant way of publishing in the electronic age we are all wasting our time. Especially from those publishers that bring out a book on electronic gadgetry. Why is this not available through the app store? Greed by the publishers? Edit: I felt enough to email the editor.
