I was moving
Around 5 years ago I was moving from Michigan to Ohio for a job. It was too expensive to call my wife on the motel phone (I was living here for 6 months before she moved with our stuff) so I looked into cell phones and discovered I could get 2 phones with 2 lines for less than I was paying for my land line in Michigan. We never bothered to get a land line once we finished moving. Why should we double what we are spending on phone coverage?
There is a negative side to this. You can only get cable and not DSL when you don't have an active land line.
