My sister and my niece (who is 17) got me started on text messaging. I am not coordinated enough to talk on my cell phone while I'm driving, let alone send a text. After trying to type text messages I can see why people who do a lot of them like a qwerty keyboard. My brother uses his at work for conveying information (was that measurement 50 or 15 inches - it can make a big difference if heard and transcribed wrong).
