Well I'd stop leaning towards the PS3 if I were you.
If you tend to use your console with online friends, I'd go for the 360.
If you prefer to play alone or with real-life friends then get the Wii.
If you have no friends and don't really like videogames go get a PS3 or cup-and-ball... you'll get the same entertainment from both.
The 360 is more of a "traditional" console, so you might wanna get it if you prefer a nice old-fashion controller.
The Wii is a more experimental and physical console, if you like lightguns and othe rmotion controls then you'll love the Wii.
If your worried about red-rings on the 360 be sure to get a NEW one, not a second hand one.
If you want to make the most of the Wii then pick up Wii Sport's Resort for the Wii motionplus, you won't regret it
