Why is this idiot so worried about this? considering the background noise in an airplane, I wear ear plugs against the jet engine noise. Some retard on a cell phone is not going to bother me. Besides, headphones with music will drown out a caller as well.
It means that cell phone users will be yelling into their phones instead of talking, and those passengers seated near engines will be screaming into their phones.
Kind of like most Nextel users.
