Pretty good, but the technical explanations were pretty light at times. I'd really like to have the narration they had and on top of that, much more details about the technical side and how it was achieved. When you talk about literature you actually quote authors, when you talk about hackers I think it's appropriate to go back to the code and what it does, too.

Seconded. One of the best books I've ever read - I honestly wish I could forget it and start over.

If you like that you will also like a book called Showstopper which is similar but about early challenges at Microsft building the NT kernel

It is funny that you mention this book. I've read Masters of Doom and just received this one. I'm excited to read it.
