Japan's transport ministry revised a law to effectively ban any handheld system that emits wireless signals, saying the electromagnetic waves could interfere with the aircraft's navigation systems. Justly, Nintendo's DS has also been smacked by the ban hammer.
Normally on American flights, passengers are asked to turn off any electronic devices until the aircraft reaches its cruising altitude, but they're free to game afterward. Let's all hope this law doesn't make its way to the States.
