My friend Scott Hurff just released a book he's been working on, focused on building and shipping great products. He has a lot of insight and knowledge packed in, on all aspects of product design, and informed by his experiences developing products and shipping in the past.

He's got interviews with a ton of really effective and influential people, there's really a wealth of info here. Haven't finished it, but I really recommend it for anyone interested in shipping better apps and projects!
