If we're talking about XUL running on a phone, sure. But the web
page rendered by the browser may still not get the physical viewport 
size. In practice context will be provide a switch i.e. if you're writing
a web app that runs offline and launches from its own icon on a device, you 
want and will get a physical viewport size. If it's a web page, you may never 
know because the browser can lie to you.
