I think I bought mine for a rather strange reason, looking back. My friend and I were heavily into Halo 2 at the time, and I think I just assumed I would keep wanting Halo games in the future so I might as well go ahead and get one. I find it odd now because I bought it just to play an Xbox game on, so there wasn't a whole lot of reasons not to just wait until a 360 game came out. I remember definitely liking the slimmer controllers though, that was a nice bonus. The sucky thing was, after Halo 2 my friend pretty much quit playing them and playing Halo games alone (even online) didn't have the same appeal to me. Sure, I played other great games like GTA IV and Skyrim, so it was worth it to own my 360 in the end. I still use it now and again to play some Guitar Hero drums when I get the urge.
