eBooks (ePubs) are too expensive. I assumed (naively) that the electronic version would be the cost of the pulp version minus the cost of the pulp and printing and also minus the cost of shipping. Author, publisher, editor still get their same cut. In fact with DRM, the price should even be less that the above since there are no used-book sales lost.
