iPod with color display Photo comes in 20GB, 30GB, 40GB and 60GB. iPod and iPod photo are now one and the same, with every white iPod boasting a full-color display. They continue to have the same controls as iPod Click Wheel but now all models have a color display like iPod photo - ideal for viewing album artwork and playing slideshows. These are considered fourth generation models along with iPod Click Wheel.
