Why exactly are you not allowed to use a notebook computer during take-

weak to cause any problems to the plane electronics.

One notebook maybe, but 50 to 100 could cause some beat frequency
problems with the avionics.

Baloney. *This has been proven to be completely false again and again.

Not asking about your state of mind here.
They, the people who really know, require that all electronic devices
be powered down during the landing and take off phases of the flight.
They don't want to take chances with passenger's electronics that may
not be assembled and tested to FCC/FAA standards, including radiation
hardness.

Sure and cellphones do the same thing according to the same ones that
believe this. *Also, having been proven to be completely false. *The
reason, as everyone else knows, is to prevent liability for these
things flying around the cabin in case of a sudden stop.

For years the airlines have been telling people to keep their
cellphones switched off at all times while on board the aircraft. Now
that they've found a way to make extra money by allowing passengers to
use their cellphones in flight, these things will suddenly be deemed
quite safe to use.

Hopefully not, or there are going to be lots of fights on board.

I believe that Emirates and Malaysia Airlines already allow them on
some flights. Ryanair have announced they intend to as well.

Chris-

During take offs and landings? Or just during flight? Big difference.
