As in, I think that Apple should make HTML5 one of their iPhone programming languages (if not the only). What have they got to lose? Oh, that's right the iPhone SDK, which is only available on a Mac. But on the other hand, not requiring an iPhone SDK (or not requiring it to be run on a Mac) AND making it super easy (via HTML5) to develop an iPhone app would encourage more people to develop for iPhone. More developers = more apps = more $$$, possibly more than they are presently making with the Mac restriction in place. They can still require that people be signed up for the iPhone Developer Program in order to submit their app to the App Store.
