We've all seen them — gaggles of teens walking together, each with their eyes glued to the screens of their smartphones, texting, tweeting, and posting. Or that couple in the restaurant with their faces buried in their BlackBerry®, iPhone®, Galaxy® or iPad®. According to the Pew Internet Project update on mobile technology in January 2014, over 90 percent of American adults own a cell phone, though the percentage among staff-age adults ages eighteen to twenty-two is 98 percent. According to the same study, about 82 percent of children twelve to eighteen years of age have a cell phone.
