Remember folks, when the power goes down so does the cable. Our local power company is now owned by a multi-nation (no CCHIT, they many be British, but still, the power grid in foreign hands, tell me that's not crazy, national security???) so we have a lot of outages. Niagara Mohawk is now Nation Grid (I write National Greed on my checks every month). I can't tell you how many times the power has gone out, both by their stupidity or a real storm issue. And everytime, the cable is down, but the good old fashioned hardline phone lines were always up and running. And in such times cell service is spotty too. Most towers have some amount of back-up, but not for too long. During the very small local outages, we still had cell service most times, but during the real bad storms and that summer black out a few summers ago it was real hit or miss....
Unless that can be resolved I will always want at least one good old fashioned hard line....
