Update: Keep in mind that Amazon was the first company to grab a noticable portion of Apple’s iTunes digital formated music business by offering MP3 files without copy protection. Amazon is using it’s dominate position in the online bookselling business to force an ugly “DRM” scheme on its customers that assumes that they are thieves.
Amazon, and publishing companies, need to recognize that they make most of their money off avid readers who are willing to spend money to support their favorite authors. Their fear driven reaction to the fear mongering of the RIAA is pushing them toward a business model that is hostile toward their best customers. They would better serve their customers, and their stockholders, by working with the customer instead of treating them like criminals.
