This book is very simple to follow, and there are variety of useful examples. A great start for gadget developers. If you want to create vista sidebar gadgets, this is the book. Your skill-set doesn't need to go beyond familiarity with HTML, CSS and JavaScript to use this book. I have read other books most of the time the examples don't work, but this book is different, all examples just work. I can say simply great book for creating gadgets and an excellent read.

Easy to understand and written brilliantly. I was able to create my vista gadget in a day.

There are numerous gadget examples which are developed through out the book. I particularly loved the Comic Strip Gadget included in the extra section of the book, that one gadget is worth the price of the book.

This is awesome book with in-depth analysis and great reading material. User friendly explanation that is even good for the starters. The book contains many topics that give detail orientation of learning and implementation. This book has very comprehensive details that explain everything and require no further explanation. 200% worth reading!!!
