There was a really good writeup about the decision process in the early iPhones where Steve Jobs ordered the UI in its own process so that the user gets instant feedback on interactions even if the feedback is a simple loading spinner. It gives the perception of speed even if a modern android phone is timed to load the same application faster. There are ways to try and achieve this in web apps but Apple's early decision to use that approach was certainly brilliant. If you call a bank and a human answers immediately...telling you to please hold...it would be a far better experience than the current press 1 for English.
