I recently finished the audiobook version of Guy Kawasaki's latest book: Reality Check, The Irreverent Guide to Outsmarting, Outmanaging, and Outmarketing Your Competition. It currently has 4.5 (of 5) stars from 49 reviewers on Amazon.
I liked the book and I recommend it to anybody thinking of starting their own business. Much of it contains material taken from Guy's blog. I didn't mind this because he's posted some very useful articles, many of which I've saved as PDF files for future reference.
I especially like that the book includes sections from guest authors / bloggers. The parts by Glenn Kelman, CEO of Redfin are very interesting and add a note of reality to the material.
