Simple topic, name something you like about each of the big three consoles and something you dislike. Note not the company just the consoles themselves.
Xbox360: Good - Lot's of gamesin varrying price.
Bad - Most of those games are First Person shooters
PS3: Good - Powerful, simply put
Bad - Consumes a good ammount of electricity
Wii: Good - Fun relativly new enthralling way to play
Bad - Not very high powered and cannot even play DVD's
It doesn't have to be a work of art at all, don't write a paper just a basic thing you like and dislike about all three.
