You can't possibly mean his "Code: The Hidden Language of Computer Hardware and Software" or "The Annotated Turing: A Guided Tour through Alan Turing's Historic
Paper on Computability and the Turing Machine"? These books are great.
Those books were both brilliant. I don't recall his tech books being "bad", at least in terms of being somehow worse the the other Windows programming books that several large publishing houses cranked in volume.
I first came across Petzold this weekend while watching a talk by Robert "Uncle Bob" Martin on the future of programming. Martin was discussing Turing's paper "On Computable Numbers" and recommended reading it and Petzold's "Annotated Turing". I currently have Petzold's book on my "to-buy" list so am glad to see it spoken of highly.
