If you are interested in knowing about how Apple/Next and Pixar companies were built and the challenges faced by Steve, do read the book. Book is all about Steve, his vision about products, his dynamism, his stubbornness and commitment to what he believes. Steve wanted a phone to be designed which had a single button for user navigation and this lead to the design of iPhone.
I remember many of the stuff from this book and one thing which one cannot forget are various means he used for rewarding the employees. To quote one particular example, first generation of Apple computers had all the names of engineers who worked in the project, printed inside the computer which is a great feeling for who ever worked on the project.
