"About a year ago, T-Mobile USA launched Hotspot@Home, a service that encourages people to drop their landline by allowing customers to roam on to Wi-Fi to get unlimited phone calls for $10 a month. Today, it is launching a follow-on product called T-Mobile @Home, which allows people to have a home phone using VoIP."

Rico says this is the wave of the future; why hang all that wire just to deliver a signal when you can clutter up the radio spectrum instead?
