Ever since PlayStation 3 owners got Amazon Instant back in April, those of us with just an Xbox 360 have been left in the lurch. No more! Amazon let loose the Instant Video app today on Xbox Live under the Video Apps marketplace, allowing Amazon Prime owners streaming access to "over 17,000 Prime Instant videos" and both Prime and non-Prime customers to purchase access to "a library of over 120,000 movies and TV episodes."
As you might've guessed, Microsoft's Kinect functionality is also part of the service, allowing you to shout "Xbox Play/Stop/Pause/etc." as much as necessary before it finally works. The app is also locked to Xbox Live Gold accounts, so, uh, no dice for you Silver folks. Sorry about that!
