Note that I read the pre-release. Didn't figure that this was super-early material when downloaded late October 2016. Proved a difficult read, often with both amusing and distracting errors. Such as "gorilla user testing", for instance. Some sentences lacked periods, lots of "than" should've been "then" and vice versa.

The book is initially discussing real world design mistakes, but later on dives deep on digital, a topic I think the author managed pretty well and broadly. Personally I'd hoped the book was a bit less digital, but perhaps this is a more novel subject compared to writing another Don Norman rip-off.
Would only recommend this book (when properly edited and finished) to design-newbies or those unaware of usability.
