Nice documentary about typewriters. I especially liked the part about the people who collect the typewriters. It was cool to see the machines owned by Earnest Hemingway, John Steinbeck and John Lennon. They were dependable, and they don't require electricity--so they can be taken to war zones and undeveloped parts of the world. They make you think about what you are writing, because it's on paper. And we still use the QWERTY keyboard today, 100 years after being invented.
