ok... so far all things listed apply to me:

cheaper than phone call... I usually hav ethe call me thing too. hehe
no long distance.... with hubby on trips a text is fine to be communicated
you can answer if you want or not... lol... and when you want to...
you can text in a boring place and go unnoticed...
you can "fake" receiving a text... and use it as pretext to get out of somewhere...
etc....


but I do have a downside to it... according some studies texting while driving has the same or more effect as if you were drunk or on narcotics... ... while talking doesn´t...

not saying anyone should do this... but when texting you have your eyesight somewhere else... while talking you can talk looking ahead of you...
