PSP Banned in Japanese airplanes

With the modifications of law regarding traveling with an airplane, Japanese government banned using WiFi devices such as computer mice, headphones and … PSP. No this is not a joke. Law which took effect on Monday, bans using PSP on a Japanese airplane, out of fright that PSPs built in WiFi might interfere with aircrafts navigational instruments. Previously, passengers were politely asked to refrain from playing games on PSP during the flight but now the fines will be imposed. And yes, Nintendo DS was banned also, if you were wondering.
