Specifically, the big point I thought interesting: at the moment ebooks seem to have a pretty small demand which falls off fast, so they sell more like limited editions than mass-market. This <i>might</i> make it difficult to justify releasing to ebook without higher prices.<p>(I don't have a strong opinion on who's right or wrong here, as I can argue it from both sides. But I'll admit I generally sympathize more with authors than anyone on this, and they seem to have the least amount of control in the publishing process.)
