I'm with you on this Sea. I've never done it and I expect I never will. Think it's mostly for kids and the hard of hearing.
Wow ! I guess I am still a kid (albeit a hard-of-hearing one).
I do text, although I much prefer to do it on my iPad than on the phone. That tiny little keyboard is just frustrating for my fingers !
But I have the iMesssage option on the iPad, so I can easily write on there and send and receive texts that way. My son, Michael, who lives out in Washington State, loves to text; so I end up texting with him, because that is how he communicates with me.
As far as Twitter, I have an account, but don't really use it. I belong to a program called BzzAgent, and they sent you products to test out. They like you to try the product and then tweet about it; so the Twitter account comes in handy for that.
FaceBook, I totally love !
I use that to keep in contact wih all of my friends and family; and see what they are up to.
My kids have dragged me into the computer age, like it or not; but I am getting pretty well adapted.
Ina, hate to tell you this, but you are in training for texting when we IM each other on the iPad.
Behold your future, Girl...
