Yes, but there is a revised edition with bright orange colors on the dust cover of the hardbound version.

The first part of the book on productivity is still very relevant. There are a few dated parts in the book regarding testing an idea.

I still recommend it to all of my friends who have not read it as the bigger picture message is one that is still very relevant today.
