I get what you're saying, but it's not really a factor for me.
1) $132 (soon to be $126) is my all-in price including all taxes and fees. If I dropped cable TV, my all-in price for internet-only would be about $62 including all taxes and fees. So adding $50 worth of streaming services from Sling or DTVN or Vue or whichever, takes me back up to at least $112. At that point, I'm not saving enough money to put up with the additional complexities and idiosyncrasies of streaming. I'd be fine with it, but my i s c & a aggie wife already has a hard enough time simply switching the TV to watch a BluRay. So it would need to be a very large savings for me to sign myself up for being the sole channel-changing agent in the house.

2) I already have Amazon Prime and am not figuring it into the financial discussion above. I do not have Netflix and have no interest in adding it. My wife would probably like it but she already has access to and watches more than enough crap TV.
3) If it were just me then I'd likely drop TV during the offseason (though there isn't really much of that since I watch Formula 1 starting in March, and watch football through December). But there's no way my wife would go for dropping the streaming TV, so it's a year-round decision for me.
Like I said, they've done some pretty careful analysis to make sure they're priced exactly where they are, for those who would consider cord-cutting. If I had a Google or AT&T fiber option for internet-only I'd have more options, but currently at my house, I don't have that.
But I do appreciate the continued discussion and insights. There will likely come a time when I'll cut the cord anyway.
