I think that Text Messaging is stupid. A phone is for talking, not pressing buttons to send a message to someone. That's what an IM program is for.
When I travel, if I'm 'roaming', it's $0.63 per minute to talk. Sending a text message costs $0.10. When all I'm doing is telling a friend who's attending the same event, "Going to panel in room 4A, out at 1:30", it is FAR more cost effective to do it as a text message.
It has its place.
