Plus is something does screw up you do not want to be the person blamed.

I saw an item on precisely this topic a little while ago, - I think it
might
have been on the "Gadget Show" on Ch.5. To summarise, the upshot
was that in
a *very* small number of cases, with a *very* small proportion of the
electronics in question, and in a *very* specific set of circumstances, it
was possible for the flight deck instrumentation to be affected. To try to
illustrate just how unlikely it is in practice, the illustrative figures
given for some of the conditions above suggested that an estimated 5% of
devices, only when within 1.5 metres of the instruments could have any
observable effect. - I.e. you'd have to be inside the cockpit, and you'd
probably need several bits of kit on you, in order to have any chance of
affecting anything....

I find it less hassle all round just to not argue with them though.... :-)

Normally the rules for the airlines I have travelled on, is for
switching off of all devices during takeoff and landing whilst the seat
belt sign is on. During the flight, I continue to use them even if the
sign is on for when you hit turbulence and never been challenged.

It is a bit silly really as things like Ipods and PC's should not
interfere with the aircraft systems otherwise their designs are crap!!
For the likes of CE testing, your equipment is subjected to outside
interference to see if it reacts and I can only think that aircraft
systems are much higher as a good few years ago I did a temperature
logger for a helicopter and it had to pass some severe tests for radio
interference. The power output from the aircrafts own radio transmitter
is higher than a handphone!! Go figure!
