I use it only when I cannot phone someone (knowing it will annoy), when people need to get something "in writing" (address etc), or when telling I'm running late or to inform more than one of my collegues something very short and factual that does not require them to respond.
So, 40-60 I think, counting those multiple receivers.
1000, 2000, 3000 SMS's a month? Don't people have things to do? Don't people have a life to live instead of "reporting" it? I'm serious, I'm a journalist and I like to report what's going on, but text chatter? Man, I really don't get it. To me it sounds like a crutch used in order to avoid being present.
yeah i mean, people have time to text? what kind of life is that they should be wasting their time in a mac related forum instead.. oh wait i could have texted about 4 people since i started typing this
