I owned one of the them for a small amount of time. I bought it from Dynamism, played with it, and sent it back. I just wasn't sure I was going to use it for anything much. But it was a very interesting little machine.
What would be very interesting, if you're so inclined, is for you to take a couple of pictures of the thing displaying ebooks and post them. I would like to see the font rendering and what not.
