If you're the type who dreads being dragged kicking and screaming into the use of a cell phone, Samsung sells their Long Range Cordless Phone. With an incredible (for landlines) 30-mile range, the set includes a caller ID-capable LCD and is able to communicate with the base-station, acting as an intercom. It includes a car charger and an outdoor antenna with 50 feet of cable that could very well violate my Homeowner's Association's CC&Rs. Either way, if you want to use your landline anywhere in town (mountains and buildings aside) without a cell phone account, this $300 option from Samsung is one to consider.
Update: Keep in mind, this sort of power may be violating FCC regulation.
