Apple gave its nano a face lift, hence Nano Chromatic. Its not as short as the previous version, 3.6 inches (90.7 mm) in height, 1.5 inches (38.7 mm) in width and weighs only 36.8 grams. Its available in 9 different colors. According to Apple the Nano Chromatic is the world’s largest small screen (makes sense?) to me it does. It has high-resolution 2-inch (diagonal) liquid crystal LCD display with blue-white LED backlight and adjustable contrast plus 320-by-240-pixel resolution that gives you 204 pixels per inch.
The Nano Chromatic supports basically the same audio formats AAC (16 to 320 Kbps), Protected AAC (from iTunes Store), MP3 (16 to 320 Kbps), MP3 VBR, Audible (formats 2, 3, and 4), Apple Lossless, WAV, and AIFF. The nano chromatic is available in 8GB or 16GB storage capacity. The 8GB can store up to 2000 songs and the 16GB gives you the capability to store approximately 4000 songs. Get the 8GB from apple online store for $149 and the 16GB for $199.
The iPod Nano Chromatic also has cool news features added to it. Now you can shake to shuffle your music. Just give iPod nano a shake and it shuffles to a different song in your music library.
