The immediately striking thing about the XDA Exec is its size: it is larger than usual because it incorporates a (relatively) big keyboard inside a clamshell design. Just like a Tablet PC you can swivel the screen and lay it flat, facing outermost, if you don't want to use the keyboard.

When you rotate the 640 x 480 pixel, 3.6 diagonal inch screen it automatically reorients from landscape format to portrait, though you can easily change the orientation manually using an icon on the Today screen.
