D810 owners, what is the good, bad and ugly about the D810?

So, I might be in the market for a D810 and want to know the good, bad and ugly about the D810 from D810 owners before I drop 3K on one plus the over priced grip, probably get the grip used.

I'm going to move this to the 'D810 all discussions, questions' thread @Snowleopard. You should read that thread from the beginning to hopefully learn what you need.
