The replacement of the mini took Apple-related websites and the press completely by surprise since, although there were rumors about a new flash memory-based iPod, there was no prior notice of the popular mini being discontinued.

Development work on the design of the iPod nano started only nine months before its launch date.<ref name="StevieWonder"> Lev Grossman

The screen also shares the same resolution as the classic. The battery and other internal parts were also reduced in size compared to the mini.

Features

Instead of the hard disk used in the iPod classic, the nano uses flash memory. This means there are no moving parts, making the iPod nano immune to skipping due to physical trauma.

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 to the computer via the same proprietary dock connector as the third-generation iPod, the fourth-generation iPod, and the iPod mini, using a USB 2.0. 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 synchronization 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 is possible to install the free software Rockbox firmware to add many additional features, including support for 15 Sound Codecs, including OGG and FLAC, JPEG image viewing, MPEG video support, and the ability to load music directly onto the device without using iTunes or similar 3rd party software.<ref> WhyRockbox

.</ref> Rockbox currently supports only the first generation Nano.

Criticisms

Unlike previous iPods, the iPod nano does not synchronize or connect over FireWire. Also, the lack of the remote connector found on the top of many previous models means that a number of third-party accessories do not work with the iPod nano. However, manufacturers have adapted and now primarily utilize the dock connector port. The first generation iPod nano did not support voice recording, although the second generation functions with third-party recording attachments. It did not function with either Apple's iPod Camera Connector or other camera connectors from third-party manufacturers,<ref>Horwitz, Jeremy (2005-09-07) "Super First Look: Apple Computer iPod nano". iLounge.</ref> but the third generation added this feature.^{[citation needed]}

Models

First generation

Advertising emphasized 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).<ref name="firstGenPR"/>

History

The nano was launched in two colors (black and white) with two available sizes: 2 GB (roughly 500 songs) for US$199 and 4 GB (1000 songs) for US$249.<ref name="firstGenPR"/> On February 7 2006, Apple updated the lineup with the 1 GB model (240 songs) sold at US$149.<ref> Apple

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.<ref> Jacqui Cheng

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$11Image:Cool.gif. Apple also opted for the 0603 (1.6x0.8 mm) surface mount technology which was just beginning widespread use in mobile phones in 2005.<ref> Hirotaka Itoh

.</ref> The mini was not only Apple's most popular MP3 player, it was still the world's best-selling player up to the end of its lifespan; and sales of the mini did not appear to be slowing down.^{[citation needed]} Steve Jobs has argued that the iPod nano was a necessary risk since competitors were beginning to catch up to the iPod mini in terms of design and features, and believed the iPod nano would prove to be even more popular and successful than the iPod mini.

Within days of the nano's release, some users reported damage to the nano, suggesting that the LCD screen had become so scratched that it was unreadable, even when the backlight was on. Many have reported fine scratches on their nano caused by microfiber cloths. Other owners reported that their nano's screen cracked with no provocation.<ref> Larry Angell

Second generation

On September 12 2006, Apple updated the nano line. The second-generation nano features scratch-resistant, anodized aluminum casing like the earlier mini's design; the multiple color choices (silver, green, pink, blue, and black) mirror that of the mini as well. However, unlike the second-generation mini, the button labels do not match the color of the nano. Instead, they are gray, like the first-generation mini, except for the black iPod which has a black click wheel. The second-generation nano features "a brighter, more vibrant display",<ref> Apple

The second generation iPod nanos also support gapless playback of audio files, a new search option, and a 40% brighter screen. The 2 GB model is available in silver only. The 4 GB was initially available in green, blue, silver, or pink. The 8 GB model was initially only available in black but red was later added. Apple claims that the second generation iPod nano's packaging is "32% lighter and uses 52% less volume than the first generation",<ref>http://www.apple.com/environment/</ref> thereby reducing environmental impact and shipping cost at the same time.

On October 13 2006, Apple announced a special edition iPod nano Product Red, with a red exterior and 4 GB of storage. For each red iPod nano sold in the United States, Apple donates US$10 to the Product Red initiative, while retaining the regular price of US$199.<ref> Apple

Endurance

Ars Technica conducted similar tests on the second generation nano as they did on the first generation. In their tests, the screen did not last as long; although the nano kept working, its screen was damaged after one hard drop on concrete. A subsequent trip through a washing machine also failed to destroy it, although it did require two days to dry before coming fully back to operational standards.<ref> Jacqui Cheng

Third generation

Apple updated the nano again on September 5, 2007 and made it available the weekend following. The 3rd generation nano features a 2-inch QVGA (320×240) screen and a shorter, wider, heavier design, with new colors. New features include browsing via Cover Flow, a new user interface, video playback, and support for new iTunes Store games. Users must repurchase games bought before a month prior to the debut of the new iPod as they are not supported. The nano is available in a 4 GB version at US$149 (UK£99.99) coming only in silver, and an 8 GB version at US$199 (UK£129.99) coming in silver, turquoise, mint green, black, sky blue and Product Red. The battery lasts for approx. 24 hours on audio playback and approx. 5 hours on video playback.

Combining elements from the previous two generations of nano, the third-generation nano has an aluminum front plate and a chrome back plate. The nano also sports a new minimalistic hold switch, similar to the shuffle's power switch, which has been moved to the bottom of the player. The 2 inch screen has the greatest pixel density of any Apple product and has the same resolution of the 2.5 inch iPod classic's display.

On October 6, 2007, Apple released a firmware update (1.0.2) via iTunes that is said to improve Cover Flow, yield faster menu navigation and fix the Video Out option.^{[citation needed]} The update was also released for the iPod Classic.

On November 28, 2007, Apple released another firmware update (1.0.3) via iTunes, which included unspecified bugfixes.
