This is the way its all going soon... cellphones that can seamlessy 'roam onto' a home basestation with a broadband/VoIP connection for ultracheap calls when at home (and no reception issues), yet when you're out and about it uses the cellular network as always. The mobility of cell phones meets the economy/reliability of landlines (eventually, once the VoIP kinks are worked out). Nice. 🙂
