Texting

I was talking with a coworker the other day and he was shocked to find out that I don't have texting. I have never had texting in the entire 7 or so years I have had my cell phone. I definitely have had my moment's of begging with my parent's to let me get texting. But now I am used to it, and content to wait another year until my husband and I get on the same plan. Actually, (this might sound weird) but I will be proud to admit that I survived all of high school and college without it! I know it can be really annoying for people to get a hold of me, but I always warn them when I give out my number- "Don't be surprised when I never respond to your text" But most of the time they forget :)

Is there anyone else out there who doesn't have texting? 

Do you think texting is a necessity to succeed in this media/technology saturated world?
