Adobe Flex 2 - Training from the source


I picked up this book today, because I have a week of holiday and how else could I better spend it than learning a new language or internet technique?
I have downloaded and tried a few excerpts, but I think it's wiser to start from the ground.
Too bad Adobe Flex 3 - Training from the source isn't out yet, but I don't think starting with 3 instead of 2 is going to make much difference for now.
Excerpts can be found here: http://www.adobe.com/devnet/flex/articles/tfs_excerpts.html

I'm a big fan of animated sites, especially if the company involved is a web-agency. Web agencies are the classic example of people creating for themselves, which is the biggest challenge to have.
