1) Reliability. Imagine you want to play some games only to find the red ring of death?

2) I just can't bring myself to pay to play online if I don't have to. Over the long run the 360 will cost you more.

3)Gameplay. I'm so used to the feel and physics of the PS2 I could'nt change. I tried the 360, did not find the games and buttons as responsive as the PS. Those transparent buttons suck.

4) MGS4, GOD OF WAR 3, Final Fantasy, Socom, Little Big Planet.

5)Built in BLUE RAY, Bluetooth, rechargeable joystick.etc!!!!
