Deitel books are great learning tools and often used as course text or soup to nuts learning guides.
Also the physical quality of the book (printing, paper choice, color, etc) make it a collectors item if your a book lover)
I had the pleasure of being a technical reviewer on this one (though the way these guys write there isn't much review to do :)
This book includes coverage of the new features in ASP.NET 3.5, Web Services, Silverlight, Winforms, LINQ, WPF and More.
