I'm in Frankfurt this week for a trade show, and as usual I have some books along. I'm planning to re-read The Diamond Age by Neal Stephenson, a favorite SF novel set in a medium-future age where nanotechnology has become pervasive, though the novel is not "about" nanotechnology - as with all of Stephenson's books, it's about a lot of interesting things that you probably wouldn't imagine finding in the same book.
But first I am reading Dreams from My Father by Barack Obama. I decided I should know a bit more about him. Obama certainly writes well and the story so far (up to high school in Hawaii) is engaging and insightful.
