Flex Released, but It's Not a Flash Killer
“Flex presentation server pricing starts at $12,000 for two CPUs and includes annual maintenance. Special pricing is available for ISVs and discounts are available to government and educational organizations in certain regions.” [1]
Unfortunately, although Flex is 10 times cooler than Flash, it is 30 times as expensive. This is quite unfortunate, since Flex is finally a decent Flash authoring environment, but it won't take off because someone at Macromedia decided to get greedy. Yet another example of Macromedia execs squandering great technology.
