James O'Donnell's recent lecture at Yale, “A Scholar Gets a Kindle and Starts to Read,” is available via YouTube:
O’Donnell discusses how the Kindle drives readers away from the nonlinear use of texts, making it more like an old papyrus scroll. It also doesn’t help books talk to each other. He says that the Kindle is better for ludic reading, or ludic ludic reading (what Velveeta is to cheese). That is to say, the Kindle supports a limited and old set of reading practices—in this sense, there is no innovation in this device.
