For the first time in recorded history, we used our cell phones more for sending text messages than making phone calls! (Knew that day would come ...)

In the fourth quarter of 2007, the average subscriber's volume of text messages shot upward by 64%, while the average number of calls dropped slightly, according to Nielsen Mobile.

Not surprisingly, users with QWERTY-style keypads sent 54% more text messages than those with ordinary keypads. 

Teenagers 13 to 17 are by far the most prolific texters, sending or receiving 1,742 messages a month, according to Nielsen Mobile. By contrast, 18-to-24-year-olds average 790 messages. 

Thanks (as always) to the New York Times for filling my day with news.
