I was once told by a flight attendant that the actual reason they don't allow electronic devices during take-off and landing is because these times have the highest likelihood of incidents, and if their was an emergency, the flight crew, it is felt, need to be able to communicate effectively with passengers without needing to be heard over headphones or competing with games, etc. I believe reading is felt to be less engaging than other forms of media, and therefore more easily interuptable. I was on a domestic flight in Australia last week, and was surprised that my entire row kept reading their kindles through take-off and landing, and the flight attendants didn't say anything, even though the announcement of no electronic devices was still enforced.
