"New open standards created in the mobile era, such as HTML5, will win on mobile devices (and PCs too). Perhaps Adobe should focus more on creating great HTML5 tools for the future, and less on criticizing Apple for leaving the past behind."
If Apple and Adobe were in good relations and this lead to Flash being ported and fully supported on the iPhone, Steve would have gone on about the brilliancy and the unprecedented potential of flash apps on the "worlds most advanced smartphone platform"... In short - I hate PR stunts, Steve is just talking out of his * again and has no real opinion of his own.
Well, not really, His point with respect to open standards is that whereas the openess is realized in a closed system (like the iPhone, iPad and iPod), the freedom afforded by HTML5, CSS and JS empower developers to build experiences that are in and of themselves platform independent. So, a single HTML5 application would run conistently across all devices that support it and since it is an open standard, there is no notion of proprietary technology at the level that HTML5 operates (again, iPhone, iPad and iPod ARE closed systems that are proprietary down through the OS level).
The future will be heterogenous, with balanced forms of open and closed systems that empower both developers and users to get the best out of general purpose computing. I'm not in the HTML5 is everything camp, but I'm also not living in lead box... I think Silverlight, for example, has a very bright future and will do well in the closed-open world (it runs on all major operating systems and will soon show up in mobile devices like WP7...).
