As I mentioned in another thread, I think I saw an IBM Model M in the facebook movie "The Social Network" in the very beginning of the movie.
Guy gets dumped by the girl he's dating in the opening scene, goes home and cuz he's mad and bored starts to prog a website called "face mash". When he gets to work he pulls out a keyboard from the drawer/below his desk and connects it to his laptop. Think that was a Model M
