@rosborne979,
Yep, for us plebs with non-web or web simple phones, texting is so so so so much easier. Of course, I could text to deb's e-mail, and she could respond and it would come to my text, but then I'd have to treat her differently than everybody in my address book, and what a pain in the ass that would be.
I was anti-text when I first got the phone (only a couple of years ago; I'm late to the cell phone game), but it is so damn convenient for "working late can you let dogs out?" or "we're at Blue Moon, have table upstairs" sorts of messages. Much better suited to them than phone calls and certainly better suited than having to check voice mail...
