I've been to the showroom comparing these two for several times now, and it seems that I still can't identify any significant difference between the two... at least nothing that I consider worth spending extra $900 for. Many friends have been telling me there should be more difference than slight improvements in overall refinement, and the stunning aesthetics of the N804. So I don't know why after around 3 times comparing them, I still don't see the point. So this coming weekend, I'm going to the showroom for my FINAL comparison, then I'll buy either the 9NT or N804, depending on what I hear. So please help me now, and tell me what the "easy points of comparison", if any, that will READILY tell the difference between these two B&Ws. Thanks.
