One of our librarians mentioned today that Amazon.com is taking a stab at the ebook, with a new style reader and model of purchase and features (for example, you can receive the newspaper on it!)
This is the Amazon link to it, and many reviews are available online already, like this one at BrightHand.
The end of paper books? Not yet in this blogger's view. There are still many issues, from cost of the reader, to it's longevity as a platform, and the important issue of having an ebook format limited to a certain manufacturer - what if you want to have ebooks from other sources? An interesting try though!
