I vote for XBOX360 because it can be modified and you can play downloaded games, it is much cheapier!
Nintendo wii is a good alternative for people like me, I have a weight problem and this makes me loose a few pounds.
with out a doubt xbox 360 and once project natal comes out in the fall, it is going to usher in a new age of gamin, just like the wii did a couple years ago.
I use to like xbox 360 until it kept breaking down on me. I'm moving to ps3, plus it has blu-ray that is upgradeable to the new 3D TV format.
all of them are good as long as you can enjoy it my purposes to playing game is just for have fun, so I don't really care if it PS3, XBOX 360 or Wii, but I love PSX
