5" or larger iphone may change US iphone users attitude on app vs web decision..On my tablet and 6" phablet I avoid apps as much as I can.. Since I disagree with you I'm curious of your smartphone size..
I want the mobile web to succeed as much as the next guy here, i am just talking about the general smartphone using population. But even for me, things like twitter/facebook/youtube are just a better experience in app form.
