The lights are on
I love 360 as much as the next guy, but as soon as I got a PS3, my 360 took a major backseat. The PS3's graphics are cleaner, it has a faster processor, free online connectivity, web-browsing, and the wonderousness that is Blu-Ray. Furthermore, it has some of the best console-exclusive titles out there, such as the "Uncharted" series and "Heavy Rain".
Don't get me wrong-I still own a 360 and love it. It has some amazing games on it, and the Live Arcade is awesome. I just love my PS3 more.
