There’s an old saying in the manufacturing world: Don’t reinvent the dongle. Or maybe it was a wheel or something. In any case, it should be little surprise that Chromecast Audio — Google’s low-cost answer to the problem of streaming your music easily all over your home — essentially is on the outside the exact same device as the new Chromecast (erm, Video).
Same circular design. Same microUSB power source. Only instead of a connected HDMI dongle, we’ve got a couple inches of 3.5mm audio cable. (And in a great yellow color!)
