Chris Anderson's WPF book available for pre-order from Amazon

WPF architect Chris Anderson has been working on a book explaining his wonderful creation for quite some time now. The book is just under 500 pages long and should be available at the end of April, but you can pre-order it now on Amazon. I can't wait to read this one to get insights from Chris as to the "why" of certain bits of WPF design. The book also has an accompanying page on Chris' site which contains a link to the first 9 pages of the book in XPS format, and will hopefully include code downloads and such when the book is released.
