Well in addition to all of the above, what also worries me are the following:
- Use of mobiles during landing/takeoff (aka how would it ever be policed??)
- Use of mobile phones adding to the number of distractions during vital safety demonstrations prior to taxi/takeoff.
- Also, what ever happened to the old "could cause interference with the aircraft systems" line always mentioned on every flight prior to departure? I mean, the use of mobiles basically says to the traveling public, that if it's ok for mobiles to be used on-board, any other electrical item should be no different.
