The Kindle is already able to read more than just Amazon DRMed content, it can handle a number of formats.
The Kindle has many flaws, but it does allow you to read a few different non-DRM formats.
If you read some of the Kindle discussion groups, you'll see people complaining about "no backlighting", and then a few days/weeks later they will be lauding the fact that it has no backlighting.
The Kindle has a built in cell receiver so that you can wirelessly browse, preview and purchase books using one-click.
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.
