On June 28, 2005, the iPod photo series merged with the fourth generation iPods. All future iPods would have a colour display (except for the iPod mini and the monitorless iPod shuffle). The iPod photo is a hard drive-based music player nearly identical to the 4G click-wheel iPod. However, unlike earlier models which were monochrome, its 220x176 pixel LCD display is capable of displaying up to 65,536 colors. It also offers hard drives in 40GB and 60GB sizes. These enhancements allow users to store and display photos on the iPod photo.
