I've only read the first 100 pages but I've seen a number of important examples where the author distills key concepts in a few pages or even paragraphs that would take other authors an entire chapter("Delegates" as one example) and yet the author's explanantion is still clearer. This book is not for programming beginners, its for intermediate or higher programmers making the transistion to .NET. This book is still useful in 2006 to explain some key concepts in VB .NET although there have been minor changes in the language since it was written.
