I mostly agree but would say wired is a better technology than wireless in terms of safety, reliability and cost. I only use wireless for an occasional phone call usually on the road in case of car trouble, with my keyboards and with my Visonic home security system sensors.

Timothy Schoechle of the National Institute for Science, Law & Public Policy in Washington, DC recently wrote a paper called "Re-Inventing Wires: The Future of Landlines and Networks" on this subject. It's available as a PDF download from https://gettingsmarteraboutthesmartgrid.org/pdf/Wires.pdf
