I found this book really accessible, and a great way to jump into Flex after a coding hiatus. However, Flex 3 is out and wouldn't compile my Flex 2 apps. I'm sure you can hack code fairly easily to update it (OK, I'm not sure but I guess), but you might want to wait for a newer edition.

This was my first book as an intro to Flex. Very helpful and would recommend to others.

If you're using a Mac. Don't bother with this book unless you know ColdFusion well. Chapter 17 and onwards are dependent on setting ColdFusion up. The book has no instruction in the book for Mac setup at all (it was said the Mac version wasn't ready at the time. Reasonable). Looked up the errata pages found nothing either. I searched the web a little, and was able to set it up, but couldn't get it to start correctly.

I then wrote to the publisher to ask for the instruction. They were quick to respond, but they don't have the answer. They had to ask the author. After more than a month and several emails. Nothing ever came about, which render this book useless to me.

From the 17 chapters I was able to put to use. The lessons themselves are not bad, but not great. Some issues were never clear. Maybe they will be mentioned at the later chapters, but I guess I'll never find out.

So, if you're using Windows, maybe, this book can work for you. But don't expect anything from the author if you ever decide to ask questions.

I've just purchased this book and started reading it. What I've seen is that the book is divided into lessons, and each lesson has different exercises. You can follow the lessons as you were at class, with a very good learning curve. So, if you want to have a solid base on this technology, you need a lot of time to do all the examples and exercises but, when you finish the book, you KNOW Flex 2.

If you're initiated and need a reference guide, don't buy this book. In other case, this is maybe the best book for learning Flex 2 with a training way.

(Sorry for my English, I am Spanish and I've tried to write the best I could)

I wasn't too convinced about this book @ the beginning. It really is perfect for any beginners, and those seeking to get familiar w/Flex. I've been designing/coding in Flash for almost a decade now, and this book sure made the transition allot easier. The only reason I gave it a 4 and not a 5 is because the examples are all related, so if you're into building up the same example as you progress thru the book, this is perfect.
