The The Book is a Kindle clone with a 7" LCD screen, Wifi, and support for Adobe Epub. It runs Linux and it has a reasonably useful keyboard. I reviewed it in August.
This general design could be the next netbook. Right now the only thing stopping that from happening is the limited software on these devices. If the Book gets hacked it will be so much more useful.
I'm also thrilled to finally meet someone who gets it. Here is why Chris started this project:
Well, that's a good question. TheBook really doesn't have the battery life to be the greatest book reading device, but the software platform is mostly based on open stuff, and it's an interesting little piece of hardware. The same LCD display that makes it hard on the battery makes it respond more quickly than the E-Ink based readers for things like web browsing and games. It might be nice to adjust the built-in software bundle so that it does more of what it does well. Also, I have one.
