Zune firmware 3.1 is available today. I havent seen the actual changelog yet, but with a quick browse through, I see it added 3 more games, Space Battle, SuDoKu, and Checkers to the existing (since 3.0) other 2 games. They have also added a "listeners like you" feature to the Zune app..... kinda like eharmony for music....
Free games and added features makes this a worthy update.
Honestly people, it is better than an iPod.... sheesh
