Interesting article about an innovation in the book publishing/buying/selling world. I'd be curious as to the price and quality of the books printed. Generally, I think it's a very cool concept. I know there are a lot of books you can get via e-book and self print, but the quality isn't there and I'm not a big fan of the e-readers I've tried out...so if there's a way to pay a comparable price and get a high quality print/bound book, I'm all for it...especially if it allows you to find obscure or out of print titles.
