Tom Hanks, yes that one, loves vintage typewriters. He has a large collection of them. There is an app i have been running on my iPad2 called Hanx from him, it simulates typing on an vintage typewriter. It has a delightful animated interface and is not bad at all for a text processor. Do try it out.
