I think you are missing what this is. This is wireless streaming to your television from anything that you can play on your smartphone, tablet, or pc.
I have AppleTV (which BTW just added ESPN (no more watching shitty AU basketball games on the ESPN3 on my iPad) and HBOGO)for the main room but nothing for the bedroom.
I was just going to order this rather then get another AppleTV for $99. However there is a major issue with this IMO, anything you stream must be on. So if you are streaming from your phone or tablet, make sure your battery is fully charged because once your device dies no more streaming. If I want to watch it from my laptop, I have to plug it in and have it in the bedroom to be able to control the video (ie pausing or stopping)
I may still get this, but I want to do more research. Quite honestly I don't see a big difference between this or Roku or AppleTV.
