I agree with your true write-once-run-everywhere dream, but I disagree with the conclusion that we build an abstraction over existing frameworks. This is essentially what wxWidgets or QT is for desktop. While these things were great, in the end what most of us wanted was actually HTML/CSS/JS and the freedom to create beautiful things that it gives us. I would argue that default looking iOS apps are already stale and we want more control (which CSS is great at giving). I am banking my business on the same thing happening long term in mobile. I agree that webview apps can't compete with native in certain situations, but devices are becoming more powerful every day and web technologies have already proven themselves with a large developer audience. Also, I think there is low-hanging fruit just in the mobile web space: making more websites work well on mobile devices.
