Personally I'm not seeing as much reason to mod the XBOX 360 as there was to mod the XBOX. At this point in time with everything the 360 can do, about the ONLY "real" reason to mod one would be to play copied games.
Yes, there will be "legitimate" uses by a minority of people.. but in all honesty can you say that 2% of the people who own modded XBOX's use them for "running linux" or "research purposes".. No.. its probably more like 0.1%.
Lets face it, you use it for XBMC and Copied Games.. The 360 gives you a media center, so what do you have left.. Copied Games!! I personally will find it hard to believe anyone can keep up this charade of not supporting pirated software when it comes to XBOX 360.
EDIT: WTF XBOX SCENE!! So its against your fucking rules to post links to "Free stuff sites" yet low and behold the text links being placed in MY FUCKING POST to benefit someone else BY YOU GUYS!! That is just fucking low!!
