All iPods have five buttons and the later generations (4th and above) have the buttons integrated into the click wheel - a design which gives an uncluttered, minimalist interface, though the circuitry contains multiple momentary button switches.

IPods with color displays use anti-aliased graphics and text, with sliding animations. The sixth-generation 160 GB iPod Classic was the last Apple product to use the original 30-pin dock connector and the distinctive click wheel. On September 9, 2014, Apple discontinued the iPod Classic. It was available in silver or black from 2007 onwards, replacing the "signature iPod white". Prior to this, all iPod Classic models were simply referred to as iPods the first iPod released in 2001 was part of this line that would be called "Classic". The "classic" suffix was formally introduced with the rollout of the sixth-generation iPod on September 5, 2007. All generations used a 1.8-inch (46 mm) hard drive for storage. There were six generations of the iPod Classic, as well as a spin-off (the iPod Photo) that was later re-integrated into the main iPod line. The iPod Classic (stylized and marketed as iPod classic and formerly iPod Video or just iPod) is a discontinued portable media player created and formerly marketed by Apple Inc.
