SkyDrive will be on Xbox 360 today.

The three primary use cases are:

1. Shared photos & videos. Share a meaningful event with your friends or family by viewing photos & videos on your TV, or view photos & videos others have shared with you through SkyDrive. Imagine being able to view cherished photos and videos shared by friends and family —like a musical performance, a kid’s birthday, or baby’s first steps—on your TV.
2. Snap and see. For Windows Phone users, snap a picture and see it appear almost immediately in your camera roll on the big screen. This feels like magic! For example, you could take a quick snapshot of your child making a funny face, fire up the SkyDrive app on your Xbox, and view it right away on your 50” screen. Just make sure you’re using the same Microsoft account sign-in for both Xbox LIVE and your Windows Phone.
3. Party slide show. Plan a great slide show to play in the background of a dinner party. For example, you could start a slide show of a recent trip for friends, or have holiday-themed photos and videos playing during a holiday party.
