I will probably relegate this to the status of most of my other tech books: more reference than anything else. It's good though, and deserving of more effort than I ultimately gave it. (Though, for the moment at least, it will have one of the spaces within reaching distance on the top of my desk.) I probably did actually "read" about 70% of it, and skimmed the rest (before leading a book club style discussion of it) last month.
If the book does have a fault, I felt like it wasn't giving enough credit to the creativity (in UI as well as game design) driving a lot of successful mobile games. It felt like it was advocating sticking with tried and true design principals when those principals have been around for so few years to be relatively meaningless. Especially when there are so many counter examples readily available.
