He concludes that the EBM is a more natural fit for a copy shop than for a book store. He had some difficulty finding data to do his analysis for whether a book store (or copy shop) could make money on an EBM, and relied on some elderly data that was then refreshed when the source had a chat with the OnDemand, the makers of EBM.
However, Alan Beatts and Nate Hoffelder remain skeptical of the Espresso Book Machine as a good fit for a bookstore, and think it would be a better fit for a copy shop. Beatts in particular notes that a bunch of services are probably needed to support the self-publishing authors who are apparently the primary users of the EBM, at least in its book store form.
