Style of the book is a bit arrogant. I guess that's the purpose since it brings many contradictory thoughts compared to main stream ways of doing business. They're message is to quit the bullshit and concentrate on things that makes you and your customers happy. They're message is that good user experience is the way to beat your opponents.
They also see growing too fast as a danger for complicating things and not as mandatory action for businesses to survive. They're hiring policy is really cautious. Their advice is to hire in the last possible moment, when all of your are just too damn busy to make something which is absolutely necessary.
I advice to read it to get you thinking. There's some things I didn't agree right away, but that's quite normal. Still I really enjoyed reading it. It's compact, full of good thoughts and some good examples. It gives the finger to many believes in current business making and working habits.
