The Xbox 360 is quickly becoming the best video-streaming device for your living room, and Microsoft has today added another useful app to the system's ranks: Amazon Instant Video.

That means any video you purchase from Amazon Instant will be watchable through your Xbox 360, and Amazon Prime members will automatically gain access to Amazon Instant's selection of over 17,000 streaming videos.

The app also comes with Kinect functionality, so you can control video playback and selection with voice commands and gestures.

Now let's hope Microsoft doesn't try to release a Kindle Fire competitor so that the two companies can continue to play nice.
