Advertising emphasizes the iPod nano's small size: it is 1.6 in (40 mm) wide, 3.5 in (90 mm) long, 0.27 in (6.9 mm) thick and weighs 1.5 ounces (42 grams). Its stated battery life is up to 14 hours. The screen is 176x132 pixels, 1.5 in (38 mm) diagonal, and can display 65,536 colors (16-bit color).^[1]

Instead of the hard disk used in other iPods, the nano uses flash memory. This means there are no moving parts (other than the click wheel and hold switch), making the iPod nano immune to skipping.

Features

The iPod nano works with iTunes on Mac OS X or Microsoft Windows (third-party software is available for platforms that Apple does not support). It connects through the same proprietary dock connector as the third-generation iPod, the fourth-generation iPod, and the iPod mini, using a USB 2.0 port on the user's computer. Although it uses the same connection as Apple's FireWire iPod Cable and can charge its battery over FireWire, the iPod nano does not support synchronizing over a FireWire connection. The iPod nano includes a stop watch and a multiple time zone clock function. There is also a combination lock feature that makes use of the click wheel to lock the iPod, and serves to secure the user's calendar and contact information. It was also the first iPod to include a new lyrics screen, modifiable using iTunes.

Colors and pricing

The nano was launched in two colors (black or white) with two available sizes: 2 GB (roughly 500 songs) for US$199 and 4 GB (1000 songs) for US$249.^[1] On February 7, 2006, Apple updated the lineup with the 1 GB model (240 songs) sold at US$149.^[3] Apple also released some accessories, including armbands and silicone "tubes" designed to bring color to the nano and protect it from scratches, as well as a combination lanyard-earphone accessory that hangs around the neck, and avoids the problem of tangling earphone cords.

Endurance

Testing by technology-enthusiast website Ars Technica has shown that even after being sat on, dropped by a jogger, dropped four times from a car moving at various speeds, then being driven over twice by the car, and finally dropped from nine feet onto concrete, the unit's screen was damaged but it could still play music. The unit finally stopped playing music after being thrown 40 feet into the air and landing on concrete.^[4]

Electronics

The iPod nano uses general-purpose integrated circuits (IC) instead of smaller, low cost custom developed chips, possibly to reduce time-to-market. This design, however, increases the number of electronic components and increases the cost. Japanese engineers estimated the component cost of the 2 GB nano as between JP¥22000 and JP¥27000 (US$185-US$227), which was high compared to the retail price of JP¥21800 (US$183) at the time. The cost of 2 GB NAND flash memory was about JP¥14000 (US$118). Apple also opted for the 01005 (0.4x0.2 mm) surface mount technology which was just beginning widespread use in mobile phones in 2005.^[5]
