Read about the changing face of telecom in this 2003 Slate article that predicts the death of the telecom land line. Here is a current article in Slate which seems to indicate the prediction coming true. Perhaps it just the logical outcome of Peter Huber's Law of the Telecosm.

Huber's Law of Geodesic Networks

Putting together Shannon's law with the law of bandwidth efficiency produces a vision of the kind of networks that will prevail. As coined by Peter Huber, they are "geodesic": short-connection, multipoint, dense arrays. The higher the frequency, the shorter the wavelength, the wider the bandwidth, the lower the power, the smaller the antennae, the slimmer the cells, the cheaper and better the bandwidth.

Huber's Law argues for wireless over wireline.
