If you've ever looked into turning a software idea into a viable product, this book is a great guide.  Clear and simple descriptions with a little humor mixed in make it easy to turn a few pages into action items.  You'll read through once to know what you are in for and then use the book as a constant reference to keep you moving in the right direction.  This book won't tell you what the right decision for your product is, but it will help force you to ask yourself good questions to make decisions with better information.  With so many unknowns in launching your own product, it makes it a little less scary to have a simple blueprint to follow to make sure you stay focused, spend your time wisely, and don't miss important facets to make your product successful.  Even if you decide to wait on launching your own product, the advise in the book will be helpful as a consultant, employee, and even in your life outside of work.
