Have you seen this list of features?
Absolutely crazy list… my favorites (lots of them are great, but these are ones that either I had already been wishing for or that I know will be a big deal to me):
- Stream WMV video from a Windows PC running Windows Media Player 11, Zune software, or Windows Media Connect.
- Play video from storage devices such as USB flash drives, Xbox 360 Memory Units, etc.
- Play video from CD or DVD data discs.
- Xbox 360 Wireless Headset support, including battery level indicator in the Xbox Guide.
- Set up automatic downloads of newly released Xbox Live Arcade trial games.
- Optionally disable notifications from Xbox Live while watching DVD movies (I’ve turned notifications off across the board because of this)
