Keep in mind that all these people screeeeaaaming "hell no" are people who are already stuck with their MBPs. Although the MBP is obviously a superior machine - I understand you 100%! I hear that little voice in the back of my head everytime see a macbook: "should I have gotten that one instead?"
Well, I had that small voice when I was buying 12" PB and 12" iBook (I bought both) a while back. After a year, I ended up selling iBook as it was not as good as PB. I have gone through that with PPC unit and I don't hear any small voice in my head when I was going through the purchasing decision making process for my MBP.
