I got one for Christmas, it's amazing (even though I have to play on my monitor because I don't have an HDTV...).
Gears of War is sick, I just finished the campaign today! Definitely the best is when you go up to someone and chainsaw them, and then their blood is all over the screen...it's disgusting at first, but then the whole point of the game becomes who can get the most chainsaw kills (and curb stops)!!
Anyway, I'd say it's pretty good, the only thing is that if you're not gonna get Xbox Live, it's kinda pointless because the entire console is centered around that.
Some of my favorite features (besides the games):
- Wireless controllers
- You can remotely turn it off with the controller
- I haven't tried it yet, but supposedly you can hook up your Xbox to your PC and stream music/video
- Chat. I've talked to some of my friends that moved recently more in the last 6 days than I have since then altogether.
