We ditched cable at the beginning of the summer. We already had Amazon prime for other reasons, but decided to sign up for hulu+ and netflix and see what we use. I think we use amazon prime the most, although once TV shows start for the year, I think Hulu+ will be used more. We won't keep all three.
We haven't missed cable all that much. Not getting the Big Ten network is the part I don't like, but it's not worth spending the cash that cable goes for these days. We have 3 very young children so there isn't much time for watching TV anyway.
We might also look into simple.tv - it's a DVR you can buy that works with the live TV you get on the antenna.
