And then again, it's going to be limited, isn't it? Like, only on weekdays? I don't care if it's free... that's lame. I don't think many of my college buddies are going to be up until 5 AM on school nights playing Live with me, they'll be doing it during the weekends (provided we're not out drinking).
I think you can access all non-gaming content with the free service. And I believe the gaming part will be more limited than that, like it will only be a few preview weekends or weekdays every month of something.
