This is the future of television and for me, allows me to watch ESPN, HGTV, Food Network and Disney legally for minimal cost. We got rid of cable a number of years ago, which made watching sports a difficult affair. But now, I can access football, Basketball, and other sports live without paying $100 a month for cable.
About the only drawbacks to Sling TV is that it doesn't include more stations (it doesn't include broadcast channels like CBS, NBC, ABC, and Fox, although I get them through a decent antenna streamed to my phone through Tivo) and that you can only watch Sling TV on one device (although I heard a rumor they might increase it to three). Other than that, I am super excited to be a Sling TV customer and am enjoying cable TV for the first time in a while. Check out the brief video below to see how it works on the mac.
