I own a PS3 and my Girlfriend owns a Wii. I think anybody who plays on just 1 system is a secret fanboy, would i consider myself one? Yes lol
Seriously though, i never really felt the need to get either a PS3 or 360

, but once i heard about additional features such as blu-ray and considering the prices of standalone devices i was sold & never looked back.
I got my PS3 April '07 and have played the crap out of it. My girlfriend on the other hand barely touches the Wii.
Fanboy Speech....
Here's my 2 cents on this generation, there is no doubting All 3 consoles have great games especially PS3 & 360, but year on year Sony have had something new to offer, Microsoft have IMO lost the plot with Kinect & well the Wii ran out of steam a long time ago.
