I didn't have a cellphone until I was in my 40's, 10 years ago. I've lived most of my life so far without one. If I had to, I could live without it again. Even so, I wouldn't want to. It makes almost everything much easier and more convenient. I could use my computer for almost everything the phone does, but who wants to carry that around all day. I think my favorite thing about my phone is the ability to pay for things with it.
