How do you load other eBooks onto the Kindle? Just add Amazon DRM.
DRM is not to prevent other files from being readable on the Kindle.
Devices like the Sony Reader, Cybook, and Kindle DO NOT have glowing LCD screens.
The Kindle is already able to read more than just Amazon DRMed content, it can handle a number of formats.
A revolutionary portable reader that wirelessly downloads books, newspapers, magazines and blogs to a crisp, high-resolution electronic paper display that looks and reads like real paper, even in bright sunlight.
