The only thing we really need cable for anymore are Astros games, playoff games (theoretically), and recorded Austin City Limits (and I could probably find those if I looked hard enough).
You'd be surprised - it's much more difficult than it should be.
I've been without cable for two years. We have Netflix and Prime and I mooch a buddy's HBO Go from time to time (I know, I'm a heathen - I don't care). I spent last week at a beach house in Bolivar that had DirecTv and I spent every single night watching the Astros, start to finish. My wife saw this and, bless her soul, said fuck it - let's get cable again.
So once August 11 hits, I will be living proof of somebody who ponied up $100/mo for America's Fattest Dancers just to watch the Astros. It pisses me off, and I held out as long as I could, but I'm over it.
The wife, bless her soul, isn't down with the proxy for the same reasons many here have listed. I just knew our shitty internet couldn't handle it so I didn't fight it too hard.
