Shear point of fact, the XBOX 360 is the worst gaming investment ever. It's a few hundred dollars when you buy it for an on going $10 a month for functionality. At least when you spend that $120 at the end of the year on a PC you get more power. The 360's hardware is already to dated to keep up with modern games. Seriously, play any game at max quality on an PC that is of equal value of what you have spent on your 360 you will see a massive difference. The PS3 is a game console, the 360 is a money pit.
Also, I like the new name Hush
