But that's the thing. U-Verse would not be using Comcast's equipment. I'm not saying AT & T are angels but I'm sure my cable bill would go down if there was competition.
Is AT&T not available in your area? Because, as you alluded, DSL runs off of the phone lines, and the TV comes down via satellite, so Comcast's equipment is not involved. It is competition, but it could be arguable whether it's an "apples to apples" comparison, since the technologies involved are different and their perceived differently.
