I have an awful time using webapps that pretend to be real apps. I think it's mostly a performance issue. Choppy scrolling, sometimes layout gets stuck in odd ways, slow repaint when screen is flipped, text entry is awkward (keyboard unintentionally gets hidden). Take Facebook's iPhone app, majority of its slowness and bugginess is caused by it being actually a web page.
