This looks interesting. I'm not a huge FPS guy, but I've always enjoyed Halo since early high school. I only game on PC, so I might just have to purchase this. Regarding Vista, it's been a terrific OS for me. I've had very little issues with drivers (TV tuner), and it's run perfectly stable for me. People that have never used the retail version are the ones who think Vista is crap. Vista was crap in beta, yes, but Microsoft has seemed to fix all the issues. And it will just get even better when SP1 is released. I am seriously thinking about getting Halo 2 now. Those graphics comparisons are like night and day.
