An anonymous reader writes A $400 million partnership between the NFL and Microsoft that replaces the old method of studying opponents from the sidelines using printed black-and-white photos with tablet computers is just one of the hi-tech upgrades to the NFL this year. From the article: "The referees are also going wireless so they can talk with each other without huddling, and coaches will sport new Bose headsets. But the appearance of Microsoft Surface tablets marks the first time players and coaches can legally use such electronic devices on the field during the game. The tablets will come into play for the first time Sunday night, when the New York Giants and Buffalo Bills play in the Hall of Fame Game in Canton, Ohio."
