Unsurprisingly, teens are the vanguard:
the typical U.S. teen mobile subscriber (ages 13-17) now sends or receives 1,742 text messages per month (compared to making or receiving 231 mobile phone calls).Yes, the comparison's a bit misleading because texting is quicker than talking. But that's precisely why texting is so handy, though don't expect a response at 3 am.
