It's entirely fair to say that the fourth edition of Computer Networks could be better, though it's perhaps not as poor as the third edition. I think the second edition provides a graceful introduction to the importance of networking layering, even if it is somewhat OSI-centric, and that it is much better for learning about fundamental principles of networking. The second edition is timeless. The fourth, not so much. But then it's trying to cover much more ground.
