Don't want to be tied to Kindle's ecosystem? These e-readers support Adobe Digital Editions

The world of e-reading was shocked by the news that Amazon is limiting users’ ability to download and transfer e-books to its Kindle devices. Although Amazon didn’t state why it’s doing this, the most likely answer is that preventing downloads bolsters the strength of its DRM. Amazon isn’t the only one that uses DRM on its books. Most e-book retailers use Adobe’s document DRM, Adobe Digital Experience Protection Technology, and you’ll find this DRM in the best e-readers.
