U Maryland English professor Matthew G. Kirschenbaum has a new book called Track Changes: A Literary History of Word Processing that tells the story of word processing from writers' perspectives; an accompanying gallery collects photos of famous authors with their first word processors (mine was an Apple //e). Pictured above: Stephen King with his Wang System 5 Model 3 word processor in 1982.
