As a someone who has used Unix for 35+ years, I feel the book is great. It actually does more to explain why things are the way they are in UNIX than any other book I've read, pro-Unix or not.. I don't agree with everything it covers and many of the complaints of the book have been addressed over the years, but it definitely still relevant today.
