This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Since you mention in your book that Java would be the steeper learning curve of the two merged technologies (if I'm not misunderstanding you), and since Swing can be deployed from the Browser, what strong case can be made then for not using Java all the way through instead of merging it with Flex. Too, what argument can be made against concerns about Flex's staying power in comparison with entrenched fully developed languages such as Java? Thanks and regards,
