Have had my Roku for around 3 years. I pay for Netflix and Amazon Prime only.
Watch those most of the time, along with free stuff on PBS like Masterpiece theater (Sherlock, etc.)
I could get by without cable entirely, but my wife and daughter are not quite there yet.
In comparisons with similar devices, Roku usually finishes on top or near the top.
The future is with this technology. The cable as we knew it, is dying.
Just got it ordered. I ordered the Roku 3. Can’t wait to get it and hook it up.
