The book is very insightful with a good overview of several areas.

What could have been better? In retrospect things could always be better in most books, there are things I would have personally like to have seen added or expanded. But for the general reader who wants a good read this flows well and is quite educational. It gets one in the mood for something geeky (whereas my wife might light candles and put on music for a romantic evening, I fire up some monitors and a good online read. This one sets the mood to make you want to learn more).
