@lithiumnk thanks for those pics. No mention of the Nutube there and seems no hardware button for it so on/off must be in touchscreen menu. Unless the 'Playback' click for the triangle home button is for the Nutube, it appears to be a secondary control for play/pause/etc. Gotta say I like navigation wheel. Color/size aside, might be easier skipping tracks without having to feel which button is the correct one to press.
