Mine has just arrived. It's gorgeous.
Yep, mine is here too, finally. Top-spec'd with VESA mount, ordered on the 2nd of November, delivered exactly one month later: december 2. Apple customer support was top notch, as always. They moved the AppleCare auto-enroll date for me to make it better in sync with the actual delivery date (actually, they moved the order date to accomplish this).
It's been said many times before, but the screen is indeed breathtaking. I own a retina MBP, but the massive size of this screen makes does make a difference.
It's dead silent BTW, I don't hear any more noise than my late 2013 model (haven't pushed it yet).
