Espresso Book Machine from On Demand Books we were of course thoroughly charmed by the Rube Goldberg nature of the thing, but were left feeling unconvinced of the practicality of it -- would people really pay money for custom-printed physical copies of classic books they can download for free? Is it really a viable choice for self-publishing? We may be skeptics, but Xerox is a believer, putting its reseller weight behind the machine (which uses not one but two of the company's printers internally), selling, leasing, and servicing the things through its retail connections. This means Espressos could start showing up more frequently at bookstores and perhaps even coffee shops early next year. Until then, watch the magic happen after the break.
