I am writing from Pearson and have seen a lot of queries about where can folks find DRM-Free PDFs of technical books now. I want to share that informit.com, a Pearson eCommerce site, sells DRM-Free PDFs from our imprints Addison-Wesley, Prentice Hall, Sams, Cisco Press, Microsoft Press, New Riders, Que, and Peachpit.
