I don't feel the need to be connected every second of the day, sure I enjoy AFF, other forums etc, but by no means does my life revolve around it. I like to disconnect from the world now and then. I also think its childish and downright disgraceful that educated grown adults would ignore a simple instruction, that is in place for the safety of everyone on the plane, just because they can't bear to be away from they're precious email or angry birds for ten minutes.
To all of you that think they know better than airline policy makers and say "I'm going to keep on using my device, bugger your simple requests QF, bugger everyone else on board, because I know better!" I know I eventually will, and possibly have, but god I hope I never share a flight with you?
