The Apple iPod Nano is a great testament to flawless engineering, design and portability. It is a mid range model and uses flash memory like the iPod Shuffle. The model has gone through three upgraded versions since its introduction. The first, second, third, and fourth generation iPod Nano include some pre-installed games like Brick, Music Quiz, Parachute, and Solitaire. The third generation can also run games which are offered by Apple at an iTunes store.
