I finished reading Windows® Presentation Foundation Unleashed over Christmas and I must say this has turned out the be the best book compared to

Applications = Code + Markup: A Guide to the Microsoft® Windows® Presentation Foundation, Programming WPF, 2nd Edition, and Essential Windows Presentation Foundation.  It wasn't because the book had color (I read it on Safari Books online which under Firefox doesn't display color( in html mode) ), The layout and flow was just the best.  Kind of  a hit the ground running format.  Thanks Adam for a great book.
