Using your cellphone as your home phone

Although there are some solutions for using your cell phones to connect to a landline phone at home and make calls, the PhoneLabs Dock-N-Talk with bluetooth seems to support the highest number of cell phones and is certainly infinitely expandable with the bluetooth integration. Think about all those unused unlimited night and weekend minutes you could be using for a one-time investment of $140. Of course, this assumes that you have great cell phone reception at your house and that you really feel the need for a landline handset that is separate from your cell phone.
