I love the xbox, but my flat mate bought a PS3 which I'm enjoying (still hate the controller though), but my point is the PS3 was A LOT easier to mod, he did it himself in like 5 minutes, MULTIMAN FTW!
the only down side is that multiman only works with firmware 3.55, so you're pretty screwed if you want to play any of the new games that require latest firmware updates (like we are at the moment)
