If you've ever flown on an airplane, you know you're supposed to turn off your electronic devices during takeoff and landing, on the theory that they might interfere with the equipment. That may change soon, as the FAA, with the support of the FCC, is considering possibly ending that ban. There are a couple reasons for this: first, it would boost productivity; second, a lot of people are skeptical as to whether they cause any problems; and third, some people have already forgotten to shut them off and they haven't caused a plane to crash yet.
Just to cover their bases, though, they're still going to have to check... well, everything against everything. All your plane models have to have all your various different generations of all your different products in them, and that'll take around two years until they figure they get the idea.
