Full size HD is 1920 x 1080 pixels, which is way too big. Streaming HD is just a waste of bandwidth unless you are streaming to a larger screen.

720p should work fine scaled to any of these devices and still better than 480i or p. The small screens are held much closer to you face that a TV screen is and you will still see better images. All iTunes are only 720p anyway and it is fine on portable devices. 1080p is overkill on portable devices, even the largest ones.
