By now, you may have heard that XBOX is changing their XBOX Live experience. The first noticeable change will be the addition of 'Avatars' (that are such an obvious steal from the Wii that it defies belief). However, this is a good addition; it allows the XBOX to become a central hub for socialization with friends; allowing you to hang with friends and chat WITHOUT being in a game. This is a bold move; but will lessen the annoying trend of 'live games' merely being used by friends to talk - but seriously deteriorating the multiplayer experience.
The other huge change is the addition of NetFlix streaming movies...this is about the most intelligent addition ever; and will increae XBOX's movie library by about 10,000 titles. This will also be a big nail in the coffin of Blockbuster since the streaming films should be included with the new altered NetFlix membership (more expensive to allow for XBOX inclusion but they're talking about 'XBOX only' subscriptions).
Good changes ahead!
