I think many coaches already do this, however their predictive results are written on paper and carried around in their binders by assistants. Every coach has a list of scenarios when going for a 2pt convert is advisable, when going for 4th down is advisable, as well as dividing plays up according to yardage & scenario.
Additionally, the amount of film that is analyzed prior to each game, as well as the amount of free-agency these days means players are so familiar with one another and opposing team's play books, that the technology already exists - in their brains.
Maybe it's the football purist in me, but I really don't think iPads would add much. In the NHL, the Maple Leafs have an iPad or two on the bench during the game (the NHL has no restrictions) and they stink.
