I have always wondered why passengers are always told to put away their cd players, walkmen, gameboy, laptops, etc during take offs and landings. They say it can cause "interference", but what exactly (instruments, radios?) gets interfered with. And if it does cause interference, why is it ok to use it when you are at cruise? Thanks once again!

The ILS and Com systems are the most critical, and these are the systems that they don't want interference with during critical phases of flight (takeoff/landing). Remember, electronic devices emit RF radiation and there are a lot of antenna cables and signal wires running above and below your seat that could pick up that radiation. Even though these systems are shielded, one never knows...
