What is native? On Android the native Java UI kit is slow and not native. You need a lot of fancy work to get fast c UI libs working on the 1000 different android devices. Goodluck with that. Browsers are probably the most optimized virtual UI machines out there. Sure not native, but I would argue that an integrated webview with proper css3 is much better optimized that using the android component framework or native draw operations. On ios things are slightly different, but also there the standard UI toolkit is a freaking nightmare. Creating general purpose UIs in a language like css feels so much better than most if not all UI toolkits out there.
