Quarante années se sont écoulées depuis le premier appel fait avec un téléphone cellulaire... Les renseignements que je présente sont tirés d'une série de sondage du Pew Research Center.
"Our recent surveys show that 87% of American adults have a cell phone, along with 78% of American teenagers ages 12 to 17. 44% of adult cell owners have slept with their phone next to their bed; 67% find themselves checking their phone for messages, alerts, or calls even when they don’t notice it ringing or vibrating; and 29% describe their cell phone as “something they can’t imagine living without.”
In short: The U.S. has gone mobile."
