The Wii U might not have much media functionality out of the box, but Nintendo would like you to think that it's a "living, breathing system" — and Amazon's just breathed a little life into it with the launch of its Instant Video app. This opens up the Wii U to Amazon's huge library of over 140,000 TV episodes and movies, with more than 30,000 available for unlimited streaming to Prime members. These can all be browsed and watched on either the TV screen or the Wii U GamePad. Following the post-launch additions of Netflix and Hulu Plus, Amazon Instant Video completes the trifecta of video subscription services previously announced for Nintendo's new console.

Update: The YouTube app is also available. While you can't watch video with the GamePad you can use it to search and display details.
