I am contemplating getting Apple TV but I don't know much about it. Is there free programing or do you need to have subscription to Netflix or hulu plus? I mostly watch documentaries on history/military/Smithsonian channels golf and movies. My daughter watches Sprout/Disney junior. My wife watches HGTV kinda stuff. None of us watches any network TV shows. Can we cut cable and get apple TV or will I need to keep some kind of service?
