Quote from article in link below "Over the last year, I’ve also outlined Apple’s efforts to starve Adobe’s Flash and AIR (and by extension, Microsoft’s me-too Flash plugin called Silverlight), at a time when pundits have insisted that Flash was a vital missing element on the iPhone and that Apple could/should/would be scrambling to port Flash to it. It might be a surprise to find that Apple’s air supply attack on Flash and its interest in dusting Windows with Cocoa are actually related."
