The difference being that web apps are supposed to be foreign. AIR is kind of like a weird stepfather who tries too hard to become a part of your life like your real father (native apps), despite the fact that he can never take his place. Web apps are like that cousin that, despite having little in common, you always have a good time whenever you visit them.
