Edit: that said, imho, the original link is somewhat misguided. It brings up an interesting question: is Apple responsible for targeting all platforms, or at least all major platforms that conform to a standard? Even if those standards aren't fully implemented among different browsers? And wtf, Apple, I wanna play checkers... Some of the demos run really well on Linux though. But I mean -- are they responsible for all platforms? Or maybe they're just responsible for not misleading people into thinking that they must choose their platform? (The issues in Microsoft's antitrust history rise again.)
Anyway, for my money I don't think the future of the web is via the traditional browser -- but I'm sort of in left field in this regard. But yeah, there are maybe deeper issues that haven't really been resolved...
Probably for small jobs where WebObjects would be overkill. And they don't use PHP instead of WebObjects they use both PHP and WebOjects, right tool for the job and all that.
They also use SproutCore, jQuery (or have used it), Gianduia, and for the WWDC schedule it seems that they use something else, possibly custom.
