KNFB Reader CEO Ray Kurzweil joined me to talk about the state of e-reading and show us a demo of Blio. Blio is a WPF reading application and bookstore that reads XPS files. They've taken it a step beyond by creating a reader that can match a book to spoken text, play embedded video, or load web content. I can imagine students with something like the multitouch Pegatron slate reading rich media textbooks that update throughout the year. Ray mentions using the cloud to allow you to go from device to device and pick up where you left off and gives us his vision of the next 20 years.
