I got my 5680 today at around 12 PM. It's incredible. I'm loading it up now.
I don't see any dead pixels and it's cruising like a charm.
Many thanks to Laura for keeping me informed, upgrading me to over-night shipping at my request and then upgrading me to Sat Delivery on PCT's dime.
PCT has been incredible throughout the buying experience!
edit: For those wondering, I ordered mine on the 3rd.
