I have a similar background in Electrical Engineering and, while I enjoyed the book, it did not change my perspective. I think the book does a good job of opening up what many programmers (and, of course, others) may see as a "black box" that they interact with on a daily basis. I recommend it to those who do not already have a fairly comprehensive of how a computer works, but if you think you pretty much already understand how transistors become ALUs and have touched Assembly, you may find it a bit boring (as I did).

I second this. I found it to be a little elementary for me since I already know these concepts.

But it is useful for a lot of people who don't know how a computer really works.

Thanks for this solid comment. Assembly is the one that I am most removed from at the moment. It is 15 years or more. So it seems like I will enjoy it at the very least.
