It’s no secret that teens and young adults do more texting with their cell phones than talking, but the margin between these modes of communication is surprisingly large. According to a new study in Great Britain, 96 percent of 16- to 24-year-olds engage in some form of text-based communication every day, be it through social networks or traditional texting. Only a little more than two-thirds of those same respondents talked on the phone every day. Trends among American youth tell the same story. About 63 percent of teens text daily, but only 39 percent use their cell phones to make daily calls.  “I’ll be surprised if, in the next 24 months, we don’t see people in the marketplace with data-only plans,” says AT&T CEO Randall Stephenson. “I just think that’s inevitable.” (Digital Trends, msnbc.com)
