I've looked at it for about 30 seconds. Kind of funky layout, lots of commentary sections peppered throughout the book. Lots of unkeyed rooms too. I'll figure it all out after I go through it in more detail, I'm sure. There's an early "errata" section where they note corrections to various things, including the map.
So there's some value being placed on this as a historical document over use (where the errata would be integrated, map corrected, etc). Haven't gone through it in any serious way yet so I don't know how that might impact actually running it. My players are a bit too low a level right now anyhow.
