The main menu screen of the iAudio 7 preview unit looks nearly identical to the menu of the iAudio 6. From left to right, you can choose from music, video, radio, recording, photos, text viewer, and settings.
From the back, you can see that the iAudio 7 (right) uses a glossy plastic backing. You can't make it out in this photo, but the text on the back of the iAudio 7 gives off a prismatic rainbow reflection. Neat.
