We've talked about it at length, but we watch just enough shows on the other channels, that we can't drop the satellite. We do plan to kill off the DirecTV and switch over to Dish in the near future; but that's simply because their automatic HD RV dish is a little over 1k cheaper. I'm tired of a 480p signal on a 1080p screen. We do use our Apple TV, but mostly to watch our ripped DVD's and BluRays, streaming video just isn't in our 5gb a month bandwidth plan.
That said, we have killed off all those services at our house, and use a HD antenna that couldn't have cost more than $30 from WalMart. It pulls in every major station in our home town, and many shows even come in with full surround sound. This is just the basic antenna that sits on the table behind the TV.
