Cnet: According to Pete Walsh, head of technology for the Dallas Cowboys, his team and a "couple of others" are considering replacing their playbooks and paper printouts with iPads. The move could save teams up to 5,000 paper printouts per game.
However, Walsh said the teams won't make the move until they're convinced that they're secure enough to protect plays. They may end up using Android tablets if they feel they offer better security. Strangely, the article doesn't once mention the possibility of NFL teams using RIM's PlayBook.
