Ebook: Learning Ext JS

I found this book hugely disappointing. While this book does contain useful information it is nothing that can't be found easily in free tutorials and forum posts. If all you are looking to do is put a simple EXT widget on a page and you can't seem to figure out how to use Google to garner the instructions... then this book is for you. However, if you are in search of solid explanation on how to build a dynamic and functional Rich Internet Application (RIA) then you have come to the wrong place.
