There are two main reasons I want to buy the Elite, and they are both personal faults.
1. I'm a sucker for anything dubbed "Collectors Edition"(I have 60+ DVDs and 85% are special edtions) as long of course it offers worthy improvements over the non-special edition, price is a non-issue reasonably speaking. (When Halo 3 comes out, I'll will at the very least buy the "middle" special edition, maybe not the helmet, that's going to depend on what the helmet is made of. If it at least feels like a real battle helmet, then I'll get it.
2. I love black. Most of my clothes are black, and I wish more electronics were black, I was really annoyed that the PS3 is the only black console for now. I did see a nice black case Wii case at IGN, they also have a chrome one I'm considering as well. (Of course I first need a Wii, cuz I still can't find one).
I have wanted an X360 for sometime, despite what the haters might say, there are a lot of good games for this system, and as much as I love the Wii, I miss graphics that make me go WOW!
Also there are some games that were exclusive to the PS3 that made me think of getting one in a few years when the price dropped, now developers are porting those same games to the X360, not all have been ported over just yet, but I'm hoping that they will be. (Final Fantasy ::crosses fingers:: )
Until Nintendo (if ever) re-establishes itself as the ultimate gaming machine (with the Wii 2) and all games are made for it, good or bad, I'm going to need a second console. Last-gen it was PS2, because it had all the good RPG's many that I am still playing since I only bought a PS2 in late 2005.
I'm also excited about the possibilities of connecting the X360 to Vista controlled computers. I know there's a lot of hate for Vista, and I agree with it only for purchasing it for an old system. If you're buying a new desktop or laptop, I see no reason not to get Vista, it may not be perfect, (don't hold your breath for a perfect OS) but it works well, and has (maybe just purely aesthetics) better features than XP.
