We cut the landline cord as well. But we still use our landline handsets with Google Voice and an Obi100, which is totally free after $35 one-time cost of the Obi device. So we still have access to great speakerphone quality and other familiar features of our legacy handsets where mobile phones typically fall short. More importantly, we don't pay for mobile minutes when we're at home. With the increased popularity of pay-as-you-go MVNOs (we use Ting), the case for VoIP is rising.
