But why React Native? Reactjs for web makes sense as browsers struggle with DOM manipulation.

Native apps rendering capacity is sub-micro seconds. Hoping for Appcelerator's dreaming Hyperloop that give us native JS capabilities.

I still plan to use ReactJs (web) within web-view.

Fills the same niche as Cordova/PhoneGap or Xamarin. It's kinda the best of both. Intuitive dev process for web developers not needing to learn new paradigms. Fully native compilation for better performance than WebViews.

Are you sure they compile to native? IIUC they use JavaScriptCore on iOS, which currently doesn't JIT. Probably good enough to drive UI and you can implement performance hungry stuff in native code.

Not sure, but it's native UI at least. The demos they showed prior to release were far more responsive than any WebView based solution.
