I have really enjoyed my Roku stick, but I couldn't put it on the television I wanted to use it on, because that TV is attached to the wall and the Roku stick sticks out to far to fit. I do enjoy all the programs that are available, so I guess I'll be buying a box for my TV in the living room.
I bought Roku in August to use at a lake cabin were cable and internet services are expensive, and over-the-air reception is not an option. I'm delighted with the picture quality and the wide variety of viewing options. Also, I like the ability to use it on a television at home that isn't on a cable box. It's small enough to take it with me anywhere.
