Hi Bill
I agree that the downside would be with the inability of connecting to a security system. I have a home in Connecticut and was looking at a system that monitors temprature and would start calling if the temps in the home fall below a set value signaling a heating problem. Taking the phone with me, well that was not an option. I found a device that you plug into an electrical outlet and plug a lamp into it. When the house temp drops to 40 degrees, the lamp lights up. I alerted my neighbors that if they see the light, call us. Nice thing is that it is a local call with Verizon Home Connect for them wherever I happen to be
