Well I've been using this 2.4 15in MBP since the second day after it was announced. I had actually purchased a 2.33 MBP a few days before and rushed for an exchange as soon as I heard about it. Congrats, I know how excited you are. Mine has been awesome so far.
As soon as I got home though, I downloaded MacInTouch's color profile and while I didn't have a problem with the default profile, the former seemed better and so Ive been using it since.
