A lot of things I want in my fantasy combination box are in direct competition with Apple so I doubt they will ever add those features.
Explain.
I don't see Apple going into competition with themselves, but they could do an awful lot to improve the TV experience, assuming they can talk the providers into playing along. The little bits of info dribbling out suggest that this is exactly what they are attempting to do. Right now, any fantasies you might entertain are in the process of being overwhelmed by a nightmare of fundamentally incompatible delivery methods. Nobody is going to fulfill your fantasies because they are all trying to do essentially the same very limited thing.

From my experience it has been far, far easier to find something I want to watch on Netflix. YMMV.
So this is the problem. I hear all the time from "cord cutters" that they are as happy as clams without cable. Apparently watching a lot of old, bad movies makes them happy.
