For some reason I have never warmed up that. Whether it's Roku or my TV or my computer seems just as easy to use the individual apps. Like, I could have my MLB.TV integrated with my YT Tv but I've never thought to do it (and I guess I actually can't if I'm not buying it through YT anyway).
I'm not real optimistic that any of this will end up working out in a way that's truly user-friendly (financially).
Also Comcast will presumably never do this with ESPN (and Bally won't either for as long as they survive, since they're with Amazon now).
