If you are already leaning towards the W3J, then I will not feel guilty giving you a nudge in that direction.
Before buying anything, make sure you read reviews and articles on it in order to get a good idea of what you are getting.
Just go to the Asus review section in these forums to read a couple of good opinions on the W3J.
Overall though, IMO it is a beautiful machine with great build qualiy that balances power and gaming ability with size.
But it may not meet your needs, so make sure you know what you are buying before you take the plunge.
