What do you mean "no cap" but they will charge you if you go over the "limit" ?
I said eventually (sometime in the future) they will charge you if you go over a limit, but not right now. That's what all these companies are moving towards, charging you after you hit your data limit. As of right now with Comcast, there is no data limit they are enforcing in my market. Within a year I'm sure that'll change.
