I was a bit bored by some parts in the beginning and the end didn't catch me since it's more about how to teach children a good relationship with technology (didn't help me that much, I have no kids) than practical tips to implement in my own life. But the middle part of this book is gold! So good, my eyes were glued to the page and I recognised plenty of the techniques that Alter described in apps and games that I use. This was an eye-opening experience!
