Hmm, I can just imagine it. There will be pax complaining that they can't have a proper telephone conversation because:
a) the IFE is too loud
b) the INF in the seat infront is crying too much - it's distracting
c) there is too much general noise in the cabin
d) poor reception / interference
What is more worrying though is with the free use of mobiles - who exactly will be paying attention to the safety briefing
I definitely agree to NO MOBILE PHONES ON FLIGHTS!
