iPads are now allowed in cockpits, even during takeoff and landing

Flight manuals are thousands of pages, so this decision makes a lot of sense, but there is a kicker:

The Federal Aviation Administration said Tuesday that pilots on American Airlines flights would be allowed to use iPads instead of paper flight manuals in the cockpit starting Friday, even during takeoff and landing. But, passengers are still required to shut down anything with the slightest electronic pulse from the moment a plane leaves the gate until it reaches an altitude of 10,000 feet.

If you can use electronic devices on takeoff and landing right next to the actual instruments, how is it possible that a bunch of people outside of a shielded and closed cockpit could possibly interfere with the planes instruments?
