ExXB,
There's actually not much I disagree with that you say - note I mentioned 'Without onboard cellphone transponder systems", by which I was referring to the "2) the use of Wifi/GSM connections between the aircraft and passengers electronic devices." that you mention. Told you I wasn't technical!
I agree re the inconsistent approach - I had previously posted asking when the CAA/EU were going to allow the use of non-receiving/transmitting devices, without realising it was already in effect - just not on the airlines I'd travelled with since then!
The 'important' line was a depreciating gag at myself. I'm actually surprised that the carriers haven't implemented the onboard systema s they could make a tidy sum with the premium rates charged.
