I think that the x box 360, the playstation and the wii are all good, but they are so different in what they do that you would look at each product for what you personally want to achieve from it.
In other words, the manufacturers should just focus on getting their product right for what it's designed to do.
The x box, is also from what I've seen very hard to get set up for the first time.
I'm guessing that the new Wii will be a big hit, at any rate.
