Personally, I would like see one of two things happening:
1. Break up Comcast and make the new pieces share infrastructure (so they would have to compete with each other).
2. Allow the merger, but with the stipulation that laws would be put in place to spur competition. Such as allowing municipalities to bulid their own network (like Chatanooga).
While few people actually have a choice, I'm still left wishing I didn't have to choose between AT&T & Comcast.
