Ipods, cd players and lap tops in planes?

Question

I live in Turkey. They don't let me play my Ipod, lap top, CD player and any other kind technological thing in planes. Both when I travel in Turkey and when I go to a different country. They say those things broke the plane's system but I'm %80 sure it's a result of 9/11. (I know because I used my CD player before 9/11 and the plane didn't burst into flames)

Is this the same in your country? Where are you from?

Answer 1

I just went to Europe from California, and we could not play any of those upon takeoff and landing.  Other than those two times, we could play it all the time.

Answer 2

Whenever i go on a plane you have to wait for 10,00o feet or something...It has something to do about the communication system

I live in the United States
