This book is perfect for beginners in Sencha Touch, but it is also suitable for advanced developers. It is based on Sencha Touch 1.1 only. Pros: * Starts virtually from scratch. * Introduces several libraries and tools like Secha Touch Charts, Sencha Animator, Sencha.io, etc. * It does explain every kind of Component: TabPanels, Lists, Maps, etc. * Explains how to move from debug to production. * Good tutorial on SASS/Compass and theming a Sencha Touch app. * Events: Listeners and Handlers explained. This is the chapter I liked most. Very easy to understand. This is crucial, because understanding events is a must, could save you hours of debugging. * The book is full of examples. You have the source code. Cons: * Some chapters cover trivial topics. * Could have spent more time to cover topics like making apps native (packaging for iOS and Android). Even if you are going to learn Sencha Touch 2.0, this book will make this learning process almost immediate.
