Greetings, everyone, from Microsoft Press. We'd just like to share that our ebooks -- available via our distributor, O'Reilly -- are DRM-free. Here's a quick description of the program (from http://shop.oreilly.com/category/ebooks.do): "You get lifetime access to ebooks you purchase through oreilly.com. Whenever possible we provide them to you in five DRM-free file formats — PDF, ePub, Kindle-compatible .mobi, DAISY, and Android .apk. Our ebooks are enhanced with color images. They are fully searchable, and you can cut-and-paste and print them. We also alert you when we've updated your ebooks with corrections and additions." By the way, we also publish a good number of free ebooks, which you can find via the "ebooks" tag at our blog (http://blogs.msdn.com/b/microsoft_press/). Our latest is the 10-chapter Introducing Microsoft SQL Server 2012, available here: http://blogs.msdn.com/b/microsoft_press/archive/2012/03/15/free-ebook-introducing-microsoft-sql-server-2012.aspx. Thanks for your interest.
