I found this book to be very well written and very eye opening.Some of the sections in the book made me think "damn he is talking about me"...which rarely happens.For all developers looking to start their own business this book is a must read.I have since listened to almost all episodes of their(Rob and Mike) podcast and needless to say I have learnt a lot in a short time.If you follow Rob's advice you will definitely save time by avoiding costly mistakes.
