I like the comparisons between halo and gears graphically are a little unfair. It's not like an apples and oranges comparison, but I will say that even if you do think they are both a realistic styling, the actual modeling is very different. Gears uses a lot of dark and grainy colors and then uses extremely harsh lights on anything metal. I personally like Halo's graphics better, just because they're more realistic instead of the a bit over indulged Gears style.

Because of the ugly and annoying windows fanboyism right here, I would like to speak with a voice of knowledge. No, I am not going to say VISTA SUCKS MACS RULE. I will however say that, while Vista is a now a competitive OS compared to OSX, it took way long for that to happen. This stuff in the feature is cool, but not revolutionary by any stretch (see Fedora Core 6 Linux)
