None.
We cancelled Directv last September. Can't pick up any antenna channels. Realized we were all watching way too much tv. Now, 7 months later, we really don't miss it much at all. Plus, I have about $85-$90 more per month to buy fishing stuff and get out and do stuff with the family. Also, more time to get chores done around the house, so I have more time to fish. We pick a few used family movies for cheap and watch those when we do watch something.
It took about a week to adjust. Anyone who has been thinking about it, I highly recommend it. I don't see us ever getting sattelite/cable again. Not once has my daughter said "hey dad, you remember that tv show we watched that one time?" But, she will recall fish she has caught and camping trips we have been on all the time. I want to make more memories for her like those. This is one of the main reasons we made the decision.
This is not intended to be a rant or anything. Just my two cents on the subject.
