Life is short. Microsoft is aggressive, and HTML5 looms. Without cross-platform support for developers and users Flex and the Flash Platform can't compete. Flex had a decent chance to become more than a promising product, but the end of that opportunity is in sight. Without strong Linux support, Flex will be a casualty of the RIA war; the question has become when Flex will cease to be a viable business decision.
This loss was preventable. I say this in the past tense, because dithering only begets more dithering. Borland's JBuilder died because of dithering, and Borland died in large part because they did not respond appropriately to Microsoft and Eclipse. Big Bill is likely to win again, using the same tried-and-true script, while playing clean. Mike
