Depends what airline your in. When I flew long haul I have to say most the crews were fairly laid back.
A Sony PSB and Ipod were certainly must have items for entertainment.
If you got bored with that there was an endless supply of porno mags in the back.
I don't know what would have happend to us and the aircfaft if the plane was searched by the "religous police" during our many transits through Dubai!!!!!!!!!!
