I don't remember where I found this link and when I went to go find it again via search it seems to have disappeared. Luckily I had it saved. Long Zheng posted a photo tour of the book from MIX10. I created a link on my iPad directly to this and it makes a cool little book to "read" or share via the slate. I've updated my Windows Phone 7 Links + Info post with this.
Here is the direct link to the PDF: Windows Phone 7 Metro Design UI Book PDF
