We have one and mostly use it to stream Pandora, which is a music service, using Hulu Plus. We had Netflix free for a month and cancelled it after a week. Physically the box does everything they advertise it to do. The main thing I can say about it is that instead of wasting $60/month for cable tv we don't watch we now only waste $8/month for the same thing. If you watch a lot of tv or Netflix movies anyway then it is definitely worth the money, at least until the Internet companies choke your bandwidth down so much they render it worthless.
Thanks very much. Movies and reading are about all I can do so I think I will give it a try. Save a bunch of money.
