I'm maybe a bit more n00bish than most, but I don't get the usecase, and the examples don't really explain it either. Anyone want to enlighten me? Is it just a way of writing an app in JS, and having something else translate it for whichever platform its on?

yes it's writing an app in JS in a way that's portable and that can use device-specific implementations of both UI Components (video for instance) and input methods (touch/mouse/keyboards/http/...)
