One item that jumped out at me after re-reading the J&A Mr. Edwards posted:
If these iPads are to be used by Air Force personnel, for official Air Force business, wouldn't these devices be locked down to prevent unauthorized installation of non-DoD/USAF applications (games, media players, et cetera)? I know Apple provides a sysadmin tool for enterprise deployment that can curb user rights on Apple smartphones and tablets, and I believe Google provides similar software.
