It also seems to only support Android. That's a terrible choice! I mean, yes, Airplay only supports iOS for mobile, but that's also a terrible choice, and Google is supposed to be the company that embraces openness. And I'm not sure how it'll be with streaming different files--does it work with Rdio or Spotify? Does it stream downloaded video? Does it have Netflix, Hulu, and Amazon on Demand? But I think it's promising, and I'm hoping Google can take these cool elements and make them into a whole that really works. It'll be available for pre-order today, and will ship in a couple of weeks.
