For me the greatest limitation of mobile safari is the lack of WebRTC. Being able to bring and develop communication focused applications via a server side application would be amazing. The web platform has countless advantages to a native only environment. 1. rapid application deployment 2. immediate fixes to address real world issues. 3. easier a/b testing push tests remotely and easily collect these updates. 4. it's freaking easy to develop html/css/js applications - the browser vendors put a lot of time an energy in testing html/css/js rendering over a huge number of use cases 5. it's cross platform it runs in more than mobile safari. IndexedDB is another one - if mobile safari or rather just safari had a working implementation of IndexedDB some interesting offline applications would be possible.
