Currently, we don't have Comcast where I live, although it's probably going to absorb our cable service, TWC. Even if they do, I won't have to worry because I don't use cable internet. Why? Because unlike any cable service I've ever heard of, our phone company (Verizon) still does its best to give us "nine nines" uptime, and outages here are very, very rare and short. I don't spend all my time streaming video or downloading torrents, so I don't need the fastest possible connection, but I do want the most reliable. And, as I used to do tech support for an ISP, the only time I ever call them is when I need a specific technical detail, such as asking if they're filtering a port I need. When they try to insist that they know more about trouble-shooting than I do, I tell them how many years I spent on their side of the phone and ask how good they are with Linux. Generally speaking, that's all it takes to get them to tell me what I need.
