Today I was asked to interrupt reading my book during take off. Well, it wasn't actually regular book, it was Kindle... I tried to argue saying that both 3G and Wireless are off, but it did not help. So I am wondering how tiny Kindle's chip can damage a huge Boeing (the same question for iPhone in Airplane Mode)? Next question is - if these devices are really dangerous for the plane, what happens if I ignore the rules and DON'T turn them off? Nobody was really checking, they just asked! And what about dozens of laptops on board stored in top baggage cells with CPUs much more powerful than those of Kindle and iPhone and still running in hibernation and stand by modes? Why flight attendants do not check them but still pay attention to my little Kindle? The Wireless/3G services are turned off which means that radio interference with on board systems obviously is not the case. Then what? Is this really pseudo-safety problem caused by inertial thinking and bureaucracy of airlines and FAA, or maybe this is SECURITY issue? Some additional information can be found here...
