Ask HN: Did anyone read The Four Steps to the Epiphany?

I am curious if someone had a chance to read this book: The Four Steps to the Epiphany http://www.amazon.com/gp/product/0976470705 and the real question if for those that did: do u think that book is worth reading today? Do u think, the messages/lessons from this book have a real, useful application in today's tech/startup world?

I am interested in purchasing and reading the book... I'm just not sure if the content (as great as it was 5-6 years) still relevant/applicable today.

Thanks in advance to all.
