Remember when they were a sort of status symbol? There's a story (possibly true) about a London commuter train. Guy in a suit is talking very loudly on a mobile "What's that? ICI are up how much? OK, sell half a million, use the money to buy more Tesco" and so on. Meanwhile, another passenger is showing signs of a heart attack, everyone in the carriage except the mobile user gathers round trying t give first aid. One goes to the loudmouth and asks to use his mobile to call an ambulance to the next station. "Clear off, I'm speaking with my stockbroker is the reply. As the heart victim starts to turn blue, a group of passengers snatch the mobile and try to ring 999... but then find the phone was one of those dummy phones used for display in the shops!
And one I know to be true: one of my colleagues part-owned a rather posh wine bar in Henley. They installed a series of small shelves in a chimney breast that was a focal point in the room, with sockets for people to plug in chargers for mobile. The yuppies would swagger up the that chimney breast to place their status symbol on display. The really serious poseurs could be seen getting out of their BMWs and calling someone to say "I'm just going in now, call me in 10 minutes", so they could later say "Oh, that sounds like my Mobile Phone" and make a big show of walking up and answering it.
