Our 16-month-old son doesnt yet watch TV, but we do let him "play" with all the video touch and SoundTouch apps. These apps kept him busy on a 6-hour plane ride, even without sound! My only only feature request would be for a voice over before video clips as an option like you have for SoundTouch. The voice announces what the baby is about to see. This is helpful if hes hogging the screen. We like to talk to him about what hes watching.
