Prepare for Xbox take-over thread.
Seriously though, Owned a PS3 once. It sucked mad dick. Owned an XBox 360 at the same time. Blew the PS3 out of the sky. Forget about Blu-Ray, anyone who doesn't download bluray rips is mad anyway. Party chat > Blu Ray. Competition > Poor online.
Wii is good too for fun, especially if you take the time to mod it.
