Nice conspiracy theory, but it ignores one extremely important point: Football is a sport, not a technological arms race. They won't allow iPads and LCD visors for the same reason they won't allow jetpacks and rocket shoes: it wouldn't be a sport anymore.
Not to mention the fact that iPads don't have the power to analyze such large volumes of information in a useful time frame anyway. Getting all that info through an iPad would require communication with some outside computing power, which they could accomplish with their headsets already if it were allowed.
I don't understand why athletic competition precludes technical competition?
As far as the ipad computational power goes I think its safe to assume that when the author says use ipads he assumes they are a frontend to a big processing backend.
