Perhaps more than any other device in Apple’s electronics arsenal, the iPod nano has changed dramatically over the years. Birthed as the iPod Mini, the first generation nano rounded off and slightly shrank the design, while adding a color screen.
The second generation nano contented itself with a mere material shift to an aluminum case, while the third generation was crunched down to a a squat while gaining Coverflow and video playback.
That squat design was reversed in the fourth generation and the display lengthened while the nano gained an accelerometer and shake-to-shuffle capabilties.
The fifth put the nano’s display on the rack and stretched it out so long it was capable of displaying 16:9 movies when held horizontally, as well as adding a video camera, voice recording, an FM radio and a pedometer to the mix.
And now here we are in the sixth generation, which shrinks the nano down to the size of a Shuffle, ditching the 16:9 display, video camera and voice recording of the previous generation in favor of a smaller form factor and a 240×240 pixel multitouch screen.
As the above infographic by DVICE shows, the nano’s been a polymorph. Who knows what other forms the nano’s shapeshifting design will take over the next half decade?.
