Overall, 99.999% of these devices harmless but I am happy to have mine switched off for the duration and not use flight mode, just in case mine is the remaining percentage point.
Yes, of course, I know all that stuff. The point is, there's no reason for the rules to be any different for a PDA/mobile in flight mode than for a laptop or other mobile electronic device.
And have we all forgotten Ryanairs and BMI's picocells already?
I'm still waiting for a documented case of a safety problem, as opposed to all the apochryphal stories . . .
