t's because the airlines want passengers to be at least minimally attentive during the takeoff/departure and arrival/landing phases of a flight. No iPod earbuds, no Boses, no Gameboys, no iPads, no Kindles. Shut up and pay attention, at least a tiny bit,
It's so basic, I'm amazed that people still wonder whether "iPads make the navs go all crazy." Has nothing to do with it.
No you're wrong, its because of electronic interference. I'm amazed you can't understand something so basic. If the airlines' intention was to get people to pay attention they would not allow, and indeed encourage, them to read books or do puzzles. Have you never heard this announcement; "We will be dimming the cabin lights for take off/landing, to continue reading please use the reading light above your seat."?
