The Börsenblatt reports that e-books were on the agenda at the recent Tools of Change for Publishing conference during the Internantional Childrens Book Fair in Bologna. In regards to childrens' books, the consensus was clear: the way of the future lies in apps, not e-books. Most apps cost about 3-4 Euros per download, which is much less than the cost of your average picture book. Yet a professionally programmed app runs about 20,000-30,000 Euros to develop, a cost that must be recouped. Yet the Carlsen Verlag's Pixi-App was downloaded more than 20,000 times in the last 3 months alone, so it seems the business model may work afterall.
