The Sony NW-HD5 is a 20GB MP3 player. What's the gimmick? If you rotate, holding it on its side, for example, the image is rotated and displayed in landscape mode instead of portrait mode. Supposedly also the function of the buttons are rotated too (so what used to be the "right" button becomes the "up" button).

I wonder if there's a way to disable this, on the off chance you actually want to view the display sideways (or upside down or whatever).
