At least on the Nexus7 when they say it's a 7" screen that's what it means. The entire 7" 16:9 display is available for playing movies/video. There's no inch lost for the bezel. It's all usable screen space.
It doesn't matter of course. Highly unlikely Apple will ever take the iPad to 16:9. My only point earlier was that IMO 16:9 would be useful for the Mini even if the larger iPads are better creation/work devices at 4:3. Has nothing at all to do with the screen real estate on any non-Apple tablet..
