When is Google going to build a Google Now for the living room to compete with Echo? I want an Echo, but I think a Google product with access to the whole Google ecosystem would be more useful to me. We know Echo will never play nice with Google (you can't buy Chromecast on Amazon is evidence). If Google built this product, the only feature they probably couldn't match would be buying products on Amazon, which I don't know if I would use anyway.
