Don't know why people are saying you're an ass for calling out glaring design flaws in a $200 book about design. I felt similarly about Sacha's book on UI, but it was only $6-$12 so it didn't seem worth complaining about. If people want to drop two coffees on something they think they'll get value from, that isn't a big deal. Additionally, the app he designed for actually exists. This is a little different from Nathan's offering because as far as I can tell, there is no end product, nor are the examples provided good indicators of good visual design or UX.
