Um. Is it just me or is this really a bad idea? I've got a cell phone also, but I happily pay the 20 bucks/month to have a landline coming into the house. Besides the warm, reassuring hum of a dial-tone, there are a lot of cases where your landline will be working long after the cell phone has become a paperweight. Especially if you live in an area with buried, as opposed to overhead, wires back to the central office. Even if the power goes out, your phone is powered from the CO (obviously) and they have both battery and generator backup systems to keep their (and your) equipment going.
