Commenter Ridd make a good point about Flash over at this story by Erica Ogg on why mobile Flash failed:
The real reason why Adobe is dropping Flash mobile support is not iPhone. It is Windows 8.
Microsoft made it very clear that they won’t allow Flash to run in Windows 8 Metro browser and they are pushing HTML5 as a platform. You do not need a crystal ball to see that without Windows’ (which runs on 95% of PCs worldwide) support, Flash is dead. It will be supported for legacy reasons for a while, but it has no future.
Windows 8 isn’t a mobile operating system–it’s an OS that aims to run well on both mobile devices and garden-variety, traditional computers. If its browser doesn’t support Flash–or any plug-in, how much longer will Flash in any form live on?
