Um, I hate to break it to you, but none of that is Palm-specific. In fact, it's all available on the iPhone already. It all comes out of WebKit, which is mostly developed by Apple. Going back further, the canvas was developed by Apple for Dashboard before it was ever standardized.

I agree that it's neat--in fact, I expected that in the way of an iPhone SDK long before the native one existed (and given the number of ex-Apple employees on the team maybe that's where the idea came from)--but I wouldn't call it a mini-revolution. It's just an SDK built on an existing open source platform.
