If anyone is curious, here are the statusbar icons from the SDK that are used for the DR800x.
Some features such as wifi and bluetooth are not in the existing DR800x devices. Some of the stylus features are interesting and either means they may appear on the DR800x or that a future update to the DR1000x will give it the DR800x interface.
The icons are 32 pixels tall so it means that the DR800x can have at most 1024-32=992 vertical pixels for document viewing (unless there is a full-screen mode).
