remarkable. it was a nice looking device. i never got to put a hand on it but really wanted to and did see it in person. in the pic i linked to you can see the page flipping being done.
however i think what this MS patent attempt it trying to patent is actually the finger touch integration with the animation. the edge of the page "sticking" to the finger etc.
i still think there is too much prior art and too obvious but i don't read it as they are trying to patent the animation.
