The embargo on electronic devices during take-off and landing is
bull****. We all know that prohibition is there to remove a possible
source of interference or lack-of-attention between the crew and
passengers in cases of emergency (which are more relavent during
taxi/takeoff/landing than during other phases of the flight).

No, it's not there for that reason. At one time, there was a real concern that
electronic gadgets could interfere with aircraft avionics, and for a brief
period in the distant pass, that was a possibility, although it's not a
problem today.

The prohibition against recieving devices (radio's and hand-held TV's -
remember those?) is really to keep the passengers in the dark about
external world events during the flight.

There is no regulation that prohibits receiving devices specifically.
