I just received an email that we have made some significant changes to the XBox 360 Experience.
Once you update your console, you will have access to new features like streaming of HD movies from Netflix.
You can personalize your "persona" by creating an Avitar.
There are more "stuff", but I thought I would just highlight 2 items. To find out more, visit: http://www.xbox.com/en-US/live/nxe/. As soon as I get home tonight, I know I'll be updating my consoles!!!!
