To calculate the overall star rating and percentage breakdown by star, we do not use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyses reviews to verify trustworthiness.
This is what computer-related books should be like. It is thorough, in depth, information packed, authoritative, and exhaustive. You cannot get this kind of excellent information from the Internet - or many other computer books these days.
I have a degree in CIS but missed out on the OS courses (took different courses instead). So years ago I bought what was at the time the newest edition of this book, and loved it. A few years later I bought an updated version, and now - even more years later - bought the newest version as of today.

Great book, only the pages are uncolored, and some features are not in the book that are only available in e-text,e-book,ePUB or whatever it is called. You need to read both to get its full potential. Defeats a bit of my purpose to reduce eye strain.
