From what I've read recent episodes of some shows will be available for up to 3 days after they air...
This is going to be a curious proposition. Most (all?) of the shows my wife and I watch are on network/OTA television, so we already get those. The only thing Sling TV was really going to offer was ESPN/ESPN2 but they have neutered that by killing the DVR functionality on those channels.
We'll give it a shot if they offer a free trial, but I'm not convinced it's going to be worth $20 a month in our house.
