The Chromecast is the tiny dongle that just keeps on giving. A mere couple of days after announcing support for a number of new applications, Google has let it be known that its $35 streamer is now compatible with Play Movies and Music on the desktop in a more native way. What this means is you will no longer have to rely on casting a Chrome tab to watch videos or listen to tunes ; instead, a Cast icon shows up within the Google Play web player and allows content to seamlessly be pushed to the device. Of course, there's still a requirement to have the Google Cast extension installed on your Chrome browser -- but this is a small price to pay in exchange for such useful functionality.
