To accommodate the new display intensive features the form factor of the Nano is substantially different. Known on the street as the "phatpod" the new Nano is wider and stubbier with dimensions coming in at a boxy 2.75 inches high and 2.06 inches wide. The thickness is reduced to a depth of 0.26 inches, or 6.5mm.
The Nano's screen at 320x240 is the same resolution as the fifth generation iPod Video and the iPod Classic. At a screen size of 2.0" Apple states that the Nano's pixel density is the highest in the world. All iPod compatible videos and photos are viewable on the Nano and are accessed with the new "Enhanced" user interface. Apple has upgraded the interface to make full use of the extra screen real estate. Now there is more information and graphics displayed when browsing through the music, photo, and video library. The unique Cover Flow navigation system where you "flip" between albums is also a new addition.
Similar to the bigger iPods custom games are supported on the Nano. Three different games are bundled with the device stored in the memory, with more games available for purchase from the iTunes store.
Despite the new form factor the Nano retains the same data connection port making it compatible with all current iPod accessories. Furthermore a new arm band will be released for runners to use with the Nike + iPod Sport Kit.
Apple rates the battery life for the Nano at 24 hours for audio playback, and 5 hours for video.
