The question I have is, how do you build Super Monkey Balls in HTML/CSS/JS? And since the answer is quite clearly you don't, the next questions are, is there any alternative that gives you pixel-level control, and if not, how can the Pre hope to compete as a platform against the iPhone and Android?
All the wildly optimistic and unfounded claims of Palm having pulled off a "mini-revolution ... implementing a full SDK in HTML/CSS/JS" or of WebOS being more than "just a WebKit browser" can now finally be laid to rest. WebOS is exactly a webkit browser, and the applications one builds for it are indistinguishable from locally-run ajax web pages.
