Great books for Beginner to expert flex development

If you want to learn flex I recommend that you start with this book:

Flash Builder 4 and Flex 4 Bible
The great thing about this book is that it starts by thinking that you are a programmer. It teaches you good practices right off the bat.
Next up read:
Enterprise Development with Flex: Best Practices for RIA Developers
The next step in the evolutionary learning of any gui framework is the eco system and third party design patterns etc. This is where this book comes and covers any thing that you would otherwise need to learn by lots of searching or blogs/twitter following :)

Enjoy!

Book Review (Software Pricing) : Don't Just roll the dice

You can down a free pdf version of this book over here : http://www.neildavidson.com/dontjustrollthedice.html

This book is from the co-founder and joint CEO of Red Gate Software Neil Davidson. The company is known most famously by its tools for SQL Server but recently many people now it by the company that bought reflector (which is the number 1 .net decompilation and IL analysis tool)

I got to know of this book from a tweet by ayende and I fully agree with his blog post : http://ayende.com/Blog/archive/2010/03/17/software-pricing-donrsquot-just-roll-the-dice.aspx

Since the book is only 65 ish pages I will keep the review short :
This book aims to answer the question "How do I price my software?" 
And it does.

Go read the book !
You will hopefully at least learn what a demand curve is :)
There is lot of stuff about perceived value and how you can set people's perception based on reference points or if you are truly innovative you can enjoy the luxury of creating a reference point for a category. People's knowledge matters. The trick in  fives ($1995) and nines ($0.99$) . Newer versions are helpful.  Linking yourself to the product (i am a telecomm bachelors wink wink).

AND SOO SOO SOO much more.
