I thought David's talk was a good one. I liked how he talked about the evolution of the book. He talked about a lot of things I was unaware of. I liked how he used to movie to illustrate the shrinking of the book.
The one thing that was really surprising was when he was talking about the book for 5-8 minutes and then just tore it into pieces. It was really surprising, but it really illustrated the connection people have with books these days.
These are my thoughts about the presentation,
