>>For video, I get 18 digital channels "free".
And by free, I mean a grand total monthly payment of $0.oo, straight off the roof antenna.<<

Me too, sear. I gave up the Satellite & cable charges for an antenna (luckily I'm not too far from the towers in downtown Chicago) and get about 27 channels mostly in digital High Def and as you said, no monthly bill. Even have Tivo-like device so my wife can record. Bought it on line - it records over-the-air signals only, and works like a charm. Even has a TV guide for setting recording times. No subscription fee there either!
