I saw a ton of things in the user interface that could improve the overall experience. It's these kind of things that Apple understands:<p>1) The map tiles shouldn't disappear when a new detail of tiles are being loaded, just draw over it.<p>2) iPhone applications have a "loading image" that is displayed whilst an app is busy launching. The browser application is just a white screen of nothingness.<p>2) Even if you're zoomed in to the max the iPhone has a bounce effect that allows you to zoom in just a bit but immediately bounces back to the maximum zoom when you release.<p>3) The zoom level should be reset when you're loading a new page. He switches from mobile Engadget to normal and the zoom level remains the same.
