even on a tablet there is precious screen real estate. with a tiny bit of code added into your "mobile app" website, it would allow anyone who uses the "mobile app" a full screen experience and get rid of the browser back button (removing confusion of what back button to hit). With the code added to the site, after browsing to the "mobile app" site, you would select the browser menu, then "add to home screen". This will add a shortcut to the website on the home screen, but moreover, it will treat the site as an app. It will not have the address bar or navigation buttons, and the "web app" will actually be treated as an app instead of a webpage. It will even show up in the taskmgr!
