Use Case V

I feel like I've said this before, but it seems to bear repeating:

Uploading and consuming media content via the game console

Streaming YouTube via Wii - via PlayThrough

SofaTube [is] a new web application allowing Wii surfers the ability to stream YouTube and Revver videos using an interface which has been optimized for widescreen televisions and longer viewing distances. Featuring large, easy to drag and drop elements, SofaTube is PERFECT for those Wii couch surfers looking for an easy way to watch someone setting themselves on fire while replying to Lonelygirl15.

Windows Home Server: User-uploaded content can be streamed to Xbox 360 - via Ars Technica

The idea behind Home Server is to provide a simplified way for home users to store their photos, music, and videos in a centralized place and make it easy to access this data from other computers and devices in the home, as well as a backup solution in case of hard drive failure. The software is based on Windows Server 2003, and users can access their files through a personalized Windows Live account. Data can be streamed to an Xbox 360 or any Windows Media Connect device for viewing on a television.

Honestly, it seems like such an obvious use case for a next generation of game console that it barely needed mentioning, or at most, could be mentioned first and we could move on to more complex use cases. But apparently not...
