Google's new Nexus 7 has the specifications to impress, but a new little and cheaper device called the Chromecast is impressing a bit more today.

The small dongle costs approximately $35 and promises to let you easily stream Internet video on a television. Plug the device into the back of a TV's HDMI port, connect it to your home WiFi network and you can then fire up videos or music on your phone, tablet and computer and watch it on the bigger screen.

'The Chromecast is easiest way to bring your favorite online entertainment to your TV,' Google Head of TV Technology Mario Queiroz said at the launch event this morning.

Google will build in the Chromecast support to the phone and tablet apps, themselves. For instance, the Android or iPhone YouTube and Google Video apps will have a Chromecast button that lets you play that video or song on the TV screen. In Chrome browsers on Mac, Windows and Chrome OS computers, the button will allow you to mirror what is on your computer's Chrome browser on the bigger screen.
It's intended to be a really simple way to watch the content you are watching on your mobile devices on a bigger TV screen. The technology allows you to do other things on your phone or tablet, for instance reading an email, while still streaming the video on the TV.

But it is simplicity and price together that are getting people excited about the Chromecast. The little device.
