My rating: 3 of 5 stars
This book was published 1st qtr of 2011, most of the research & data is over 4 years old. Apps change significantly year over year. Add to that the fact that Apple iOS is now at 8.1.2 and the current Model is a iPhone 6s, 3 model newer, it would be great to see a re-write or an update of some type. Also, with Microsoft abandoning App TAG, which was used extensively throughout this book, you cannot reach much of the author’s insights.
I would guess that the author’s: Dan Marcolina’s website has updated info.
