I own a wii, so I'm part of that problem.

Let me break my other statement down for you:

The 360 is turned on and off 4-5 times a day as different people play it for different reasons.

The PS3 is turned on/off 4-5 times a week (max) for watching movies and the occasional game/demo.

The wii is turned on/off 2 or 3 times a month max. Sometimes whole months pass and it doesn't get turned on at all.

So, the numbers will tell you that I have bought 1 360, 1 PS3, and 1 Wii, but the actual enjoyment derived is not equal like those numbers might sort of indicate.

But yes, a thread with a title like this is a can of worms, indeed!
