That was the interesting part for me, too. I am confused that none of the other comments in this thread touch on that. At first I thought maybe there is a third class of phone that we are omitting, where there is no option for a native app, and so the browser is used. But I don't know what mobile device that would be. Certainly not a nokia phone (though maybe oneday!) I personally started using Safari on my iOS for gmail. The HTML5 experience is simply better than iOS native email experience.
