Marketing people try to categorize people by building profile in order to sell them the most appropriate stuff. I've listed below few so-called "profiles" : 'balanced enjoyers', 'inside explorers', 'cool followers', 'status seekers', 'asian aspirers', 'trendsetters' (this one is too simple :), 'fun loving youth', 'professional pioneers', 'selective pioneers', 'practically phoners'... Jacques Chirac is the prototype of a cool profile : 'grandfather's phone' as told him the swedish prime minister, so cool !

I don't know whether their marketing studies takes into account the real practice/use of the mobile devices by potential users but those categories sounds too good to be relevant :(
