My Thoughts
If you want to cut the cable from your life Sling TV may be a good option. You have complete control of your subscription on a per month basis. While the offering is limited it does seam to have the majority of channels one would need. Some of the obvious omissions are SyFy, FOX, BBC America, and On Air channels. You can handle the On Air Broadcasts with an antenna. However some of the other channels would be difficult to get without a subscription service. If you can live without them, then it's not a bad deal. The user interface is nice and flattened with drill through to advanced functions. While not greatly documented the Sling TV Blog and Help pages provide great info on how to navigate the application. Keep in mind Sling TV is just starting out. They have been adding to it since they went public so we can hope that the channel offerings will only get better.
