We don't have cell phones. I just don't see the point of them. I'm not fond of using my land line, so I'm not about to be happy if someone calls me at the grocery store. But I did a cell phone built in to my Explorer when I was installing DirecTv a few years back. I used to keep it turned off so that the office couldn't call me.
Anyway, I'm with plateman. I may buy one of those handy dandy prepaid units off the shelf somewhere and avoid contracts. I just want it for my wife's daily commute. That way she can call me and tell me that she got a flat tire and is now being clubbed and gangbanged by state troopers in the back of a cruiser.
