They are all females.
The Wii is a cute and sexy farm girl. People may find cool to say that girls from the big city are hotter and smarter but they did not give Wii a chance.
The PS3 is like a 40 year old feminist. She is rich, single and powerful. However she demands so much that no one meets the requirements to play with her.
The Xbox360 is a girl that everyone enjoys spending time with. Even so she is the psycho bitch kind. Spend too much time and she gets agressive and may even kill herself.

"You are for ever angry, all you care about is intelligence, but I repeat again that I would give away all this superstellar life, all the ranks and honours, simply to be transformed into the soul of a merchant's wife weighing eighteen stone and set candles at God's shrine."
