My buddy [Chet Haase][1] has written an excellent book on Flex 4, called "[Flex 4 Fun][2]". Chet's humor, insight, and concise examples make this a "fun" way to learn Flex. Artima.com has posted some excerpts from the book to give you an idea of what to expect. Check out these great snippets:

  * [Bend your Pixels with Flex 4][3]
  * [States and Components in Flex 4][4]
  * [State-Specific Property Values in Flex 4][5]
  * [Graphics in Flex 3 and Flex 4][6]
  * [State Transitions in Flex 4 for Intuitive UIs][7]
  * [Stroke of Genius: Drawing Lines in Flex 4][8]
  * [Fills in Flex 4: It's What's on the Inside that Counts][9]

If you are just getting into Flex or haven't yet made the switch to Flex 4, then this is a great book to buy. You can buy _Flex 4 Fun_ on either [artima.com][2] or [amazon.com][10]. Have "fun" learning Flex 4! :)
