Well, duh! :)
A few quotes (and observations) from the article:
The connection between American teen and thumb-tapping keypad is so strong that more than four of five adolescents say they have slept with their cellphone in or near their bed, according to a report released Tuesday by the Pew Internet and American Life Project. Some keep it under the pillow, to awaken for late-night texts. Others use the built-in alarm to wake up.
Actually, Milady does that, using the phone for an alarm clock.
Indeed, the most vivid change surrounding cellphone use was the rapid increase in text messaging, researchers said. In an 18-month period, the number of teens who text every day rose from 38 percent to 54 percent.
In real numbers: The median daily total that teens send and receive was 50 -- or 1,500 a month. Girls typically send and receive 80 texts a day, and boys come in at 30.
The average adult racks up 10 text messages in a day.
Heh. I'm lucky if I do two SMS's a day.
