While there MAY be the slight possibility from interference from some devices (they can't test them all when they're designing the systems), the real reason is to try to save the flying public's asses when the crap hits the turbofan. All kinds of unsecured objects, be they iPads, laptops, or other devices, connecting with a skull at 100 knots can be fatal. Furthermore, if you're zoned out listening to the latest One Direction hit on endless repeat through those $300 headphones and emergency instructions need to be given, you won't hear them. It's the same reason the seats and tables need to be up. They get in the way if an evacuation is needed.
