Ideally, DRM schemes are used by publishers to safeguard ebooks, and media in general, against piracy. The scheme limits you to read the e-books with Kindle devices or other devices with Kindle App installed.
Almost all kindle books are locked down with Digital Rights Management (DRM) scheme. You love your kindle e-books, but you hate the DRM. However, as lovely and appealing as the kindle is, that doesn't make it everyone's choice, and due to the Amazon kindle's DRM protection, books we purchased from amazon, books we rightfully own, cannot be read on other devices such as nook or cell phone. E-ink and the ocean of books at make it such a pleasant buddy to spend time with.
Kindle is Amazon's revolutionary e-reader, a delighted device in enhancing the reading experience.
