Okay we have now been with Comcast/Xfinity for about six months and my wife hates the cable side of it. I was fine with the stand alone internet wh. But that's another story. Since we've seen what is available day in and day out on basic cable service my wife now wants to eliminate it. So she was looking into Sling and their offer of a Roku device. I know absolutely nothing about this Sling, Roku, Chromecast, App!e and Fire TV ****. I just assumed it's another source for streaming content. So what's the hot ticket here?
