I have a home phone, an office phone, a personal cell, and a work cell. And I really don't care to be that connected.
I thought about ditching the home line, but I like having the back up to the cell phones and a local line. My cell is not local, but that's the number I have had for the last 4 years and because I moved suddenly, the only number most of my friends have for me.
My work cell is Verizon and I just changed my personal cell from Verizon to Cingular. When one phone does not have a signal, the other one usually does, which is handy. My work has a policy that none of their technology can be used for personal use, but they have no complaints if I pay for it!
