The Apple Watch was a gift. As a mechanical watch guy, I had shown very litte interest in the Apple Watch. Once I found one on my arm, however, curiosity took over and I became fascinated. But what to do with it? My quandary lead me to several YouTube videos but I quickly tired of hipster ramblings about tips and tricks. Ugh. So off to the bookstore I went for a book and was delighted to find this newly released one. The wealth of thoughtfully organized information and graphics made me a fan. Notably, this is not a book that required me to read it from cover to cover (and I haven't). It is a reference book, nicely indexed, that I can go to when I have a question and find the answer I need. I always find myself thumbing through and finding other tidbits that I otherwise might never have found. Bottom line: the few bucks I spent on this book have made the $600-plus gift a useful tool rather than a cool toy. Five stars!
