iPod Nano (trademarked, marketed, and stylized as iPod nano) is a digital media player designed and marketed by Apple Inc.. The first generation of iPod Nano was introduced on September 7, 2005 as a replacement for iPod Mini.^[1] It uses flash memory for storage. iPod Nano has gone through six models, or generations, since its introduction. The current "sixth generation" iPod Nano supports FM radio, a pedometer, and a 39.1 millimetres (1.54 in) square 240×240 display with a multitouch interface.

Supported audio formats

• AAC (16 to 320 kbit/s)
• Protected AAC (from the iTunes Store)
• MP3 (16 to 320 Kib/s, including variable bitrate files)
• Audible (formats 2, 3 and 4)
• Apple Lossless
• AIFF
• WAV
• MP4

Development

Development work on the design of the iPod Nano started only nine months before its launch date.^[2] The Nano was launched in two colors (black and white) with two available sizes: 2 GB (roughly 500 songs) and 4 GB (1000 songs).^[1] On February 7, 2006, Apple updated the lineup with the 1 GB model (240 songs).^[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 tangled earphone cords.

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¥ 22,000 and JP¥ 27,000 (US$ 185-US$ 227),^{[citation needed]} which was high compared to the retail price of JP¥21,800 (US$183) at the time.^{[citation needed]} The cost of 2 GB Nano flash memory was about JP¥14,000 (US$118).^{[citation needed]} Apple also opted for the 0603 (1.6x0.8 mm) surface mount technology which was just beginning widespread use in mobile phones in 2005.^[4] The iPod Nano uses a PortalPlayer PP5021C "system on a chip" with dual embedded 80 MHz ARM 7TDMI processors.^[5]

Reception

The first generation iPod Nano packaging.

The size of the package was reduced 50 percent with the introduction of the second generation.^[6] The fourth and fifth generation packaging mimics this packaging, while the third generation used a larger but otherwise similar version of it.

The initial consumer response to the iPod Nano was overwhelmingly positive and sales were heavy.^[7] The Nano sold its first million units in only 17 days, helping Apple Inc. to a record billion-dollar profit in 2005.^[8]

Apple's release of the iPod Nano as a replacement for the iPod Mini was viewed by many as a risky move.^[9] 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.^[10] On September 27, 2005, Apple confirmed a small percentage ("less than 1/10 of 1 percent") of iPod Nanos shipped with a faulty screen and agreed to replace any Nanos with cracked screens, but denied the iPod Nano was more susceptible to scratching than prior iPods.^[11] Apple started shipping iPod Nanos with a protective sleeve to protect them from scratches. In October 2005 a class action lawsuit was filed against Apple, with the plaintiffs seeking reimbursement for the device, legal fees, and "unlawful or illegal profits" from sales of the iPod Nano. Lawyers for the plaintiffs claim that the devices "scratch excessively during normal usage, rendering the screen on the Nanos unreadable, and violating state consumer protection statutes".^[12] Similar lawsuits were later filed in Mexico and the United Kingdom.^[13] As of early 2009, Apple is in the process of settling a court case over the scratched iPod Nano screens, it has been suggested for Apple to set aside $22 million to refund users. A Judge will need to sign off the terms by April 28, 2009.^[14] Some commentators such as BusinessWeek's Arik Hesseldahl have criticized the lawsuits. Hesseldahl dismissed them as "stupid" and suggested that they benefitted "no one but the trial lawyers," but also suggested that Apple could have avoided litigation by offering "full refunds on unwanted Nanos" instead of charging a re-stocking fee and lengthening the return period from 14 days (when purchased through Apple retail or online) to 30 or 60 days.^[15]

Incidents

In Australia, an iPod Nano caught fire while being charged on a PC.^[16][17] Since the limited warranty was expired, the consumer was not able to get a replacement right away.

Another iPod incident happened in the Hartsfield-Jackson Atlanta International Airport while a man was working in the airport.^[18] His iPod Nano set his pants on fire. Apple Inc., refused to release a statement regarding this issue.

In addition, an iPod Nano sparked in Japan in January while it was recharging.^[19] Although no one was injured during the incident, Apple Inc. investigated the incident.^[20] It was reported on August 19, 2008 that 17 incidents of abnormal overheating with first-generation iPod Nano units while recharging had been reported in Japan, including cases in which tatami mats had been charred.^[21] On August 10, 2010, Apple Japan released a statement saying that it would replace any iPod Nanos that overheated.^[22][23]

On November 11, 2011, Apple announced the iPod nano (1st generation) Replacement Program, intended to address concerns over overheating batteries.^[24] Customers with affected devices can fill out a claim form to confirm eligibility for replacement. Defective devices will be replaced within six weeks and will carry 90-day warranties. Customers who have personalized iPod nano devices will not be able to receive personalization on their replacement devices.^[25]

History

First generation

On September 7, 2005, Apple introduced the iPod Nano at a media event with Steve Jobs pointing to the small watch pocket in his jeans and asking, "Ever wonder what this pocket is for?"^[26] Advertising emphasized the iPod Nano's small size: 40 millimetres (1.6 in) wide, 90 millimetres (3.5 in) long, 6.9 millimetres (0.27 in) thick and weighs 42 grams (1.5 oz), its stated I battery life of up to 14 hours, and its screen of 176×132 pixels, 38 millimetres (1.5 in) diagonal, displaying 65,536 colors (16-bit color).^[27]

Second generation

On September 12, 2006, Apple updated the Nano line. The second-generation Nano features scratch-resistant, anodized aluminium casing like the earlier Mini's design; the multiple color choices (silver, green, pink, blue, and black) mirror those 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",^[28] a battery life upgrade (from 14 to 24 hours), and doubled storage sizes with the new 2, 4, and 8 GB models (compared to the previous 1, 2, and 4 GB models). The second generation iPod Nanos also support gapless playback of audio files, a new search option, and a 40 percent brighter screen. The 2 GB model was 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 Product 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",^[29] 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.^[30] On November 3, 2006, Apple introduced a red 8 GB model, due to "outstanding customer demand", while also retaining the same price point of the black model with an equally large storage capacity.^[31]

On December 26–27, 2006, Apple's website and servers crashed due to thousands of people downloading iTunes software since so many iPods were sold that Christmas season.

Third generation

Apple updated the Nano again on September 5, 2007. The third-generation Nano featured a 2-inch (51 mm) QVGA (320 x 240) screen and a shorter, wider, heavier design, with new colors. New features included browsing via Cover Flow, a new user interface and video playback. Users had to repurchase games bought a month prior to the debut of the new iPod as they were not supported. The Nano was announced in a 4 GB version coming in silver and an 8 GB version coming in silver, turquoise, mint green, black, and Product Red. The battery lasted for approx. 24 hours on audio playback and approx. 5 hours on video playback. On January 22, 2008, Apple released a pink version of the 8 GB iPod Nano.

Combining elements from previous generations of the iPod Nano, the third-generation Nano had an aluminum front plate and a stainless steel back plate. The Nano also sported a new Minimalistic hold switch, similar to the iPod Shuffle's power switch, which had been moved to the bottom of the player. The 2-inch (51 mm) screen had the smallest dot pitch of any Apple product, having the same pixel count as the 2.5-inch (64 mm) display of the iPod Classic.

On October 6, 2007, Apple released a firmware update (1.0.2) via iTunes that was said to improve Cover Flow and yield faster menu navigation.^[32] 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. January 15, 2008 saw the release of version 1.1, which added support for iTunes movie rentals, music song lyrics support and included more unspecified bugfixes. Apple released update version 1.1.2 in May 2008 and version 1.1.3 in July 2008 with even more bug fixes.

Fourth generation

Fourth generation iPod Nano.

At the Apple Let's Rock Event on September 9, 2008, the iPod Nano 4th Generation was officially announced.^[33] It returned to the narrow form factor of the 1st and 2nd Generation model, while retaining and rotating the 51-millimetre (2.0 in) screen from the 3rd gen model. It was also thinner than the 1G, 2G and 3G, measuring 90.7 millimetres (3.57 in) tall by 38.7 millimetres (1.52 in) wide by 6.2 millimetres (0.24 in) thick, and weighing 36.8 grams (1.30 oz). It had a curved aluminum shell and glass screen (the glass screen being held in place with nothing but the shell). Apple claimed the battery would last 24 hours of music playback, and only 4 hours of video playback, compared to the 5 hours of the previous generation.

The six previous colors (silver, black, mint, turquoise, berry red, and rose pink) were replaced by silver, black, purple, light blue, green, yellow, orange, red, and pink, for a total of nine, although the Product Red color was only available directly from Apple (website and retail stores). Apple marketed the new colors as "nano-chromatic". Also added was an accelerometer which allows the Nano to shuffle songs by shaking it, the option between portrait and landscape display modes by tilting the iPod left or right, and access to Cover Flow when tilted sideways.^[34] Videos, however, could only be played in landscape mode. The user interface was also refreshed, adding a more stylized look in keeping with the new hardware design. It included a new voice recording feature which started automatically when an Apple compatible microphone is plugged in. It also included the new "Genius" feature, introduced by Apple the same day. The Genius feature automatically creates playlists based on a selected song using an algorithm built by Apple.

It was additionally touted as "the most environmentally friendly iPod Apple has ever made", containing arsenic-free glass and a BFR-, mercury-, and PVC-free design. It was also claimed to be highly recyclable. The iPod Nano 4G was shipped in cases similar to the 2G ones with the clear view in the front, and is marketed in three models: 4 GB (limited production to Europe only) and 8 GB and 16 GB. Limited quantities of an unannounced 4 GB model surfaced in various markets.^[35] Also, the iPod Quiz game was dropped and replaced with a Maze game which makes use of the iPod's accelerometer similarly to such games on the iPhone and iPod Touch.

The fourth generation dropped support for charging via FireWire. "This change means that any dock accessories that use the dock connector's FireWire pins to send power—many older speakers and car chargers, for example—will not charge the 4G iPod Nano."^[36]

Fifth generation

Fifth-generation iPod Nano camera and microphone.

At Apple's September 9, 2009 event, a fifth generation iPod Nano was unveiled with reduced prices on the larger model (at the time of release, the 8GB was priced at $149 and the 16GB at $179), a larger, 56.3 millimetres (2.22 in) diagonal screen (up from 50.8 millimetres (2.00 in) in third and fourth generation iPod Nanos), which is also wider,^[37] integrated video camera with 16 special effects, microphone, FM Radio with iTunes tagging (via RDS) multiple radio regions including Americas, Asia, Australia, Europe, and Japan.

It also includes Live Pause, a built-in pedometer, Nike+iPod Support and speaker (features more anticipated with the iPod Touch).^[37][38]

The headphone jack and dock connector swapped locations so that the headphone jack is now to the left of the dock connector. Therefore the fifth generation iPod Nano uses a different Apple Universal Dock insert than the fourth generation.^[39]

The fifth generation iPod Nano has nine finishes: Silver, Black, Purple, Blue, Yellow, Orange, Product Red, Green and Pink. All have a glossier, shinier finish than the fourth generation. Just like the 4G iPod Nano, Product Red and the yellow Nano are only available on the Apple Online Store and Apple Retail Store .

Its standard features include picture viewing and video playback. This model also has the Genius Mix feature installed.

Sixth generation

Sixth-generation iPod Nano.

At a media event on September 1, 2010, Apple announced the sixth generation iPod Nano, which among many new features, is designed around a high resolution square touch-screen.^[40]

The device now features a smaller 1.54 inch multi-touch screen with a lower resolution of 240×240 pixels but a higher pixel density of 220 pixels per inch,^[41] as opposed to the larger 2.2 inch screen on the iPod Nano 5G. The device has a 0.39 watt-hour battery rated at 3.7 volts, giving a capacity of 105 mAh,^[42] and specified to give 24 hours of music playback on a single charge. The device takes about 3 hours for one full charge. The device retains the same 30-pin dock connector as previous generations. The new iPod Nano has lost the previous generation's video camera, built-in voice recorder (although plugging in headphones with a built in microphone will reveal a Voice Memos app) and built-in speaker, and games. It has also lost support for video playback,^[43] but music videos and video podcasts (vodcasts) can be synced onto the device, and the audio from them will play on the device, with a single key-frame shown on the screen.^[44] It still includes the Nike+iPod fitness option as well as an FM radio tuner. It has a black on white screen contrast option and other accessibility options. The 6th generation iPod Nano has the same price point as the 5th generation device. However, many consumers believed that the sixth generation was a downgrade, because it lacked some features that the previous versions had, such as the video camera, video playback, speakers and the click wheel.

A firmware update (version 1.1) for the Nano was released on February 28, 2011. The update added the ability to change songs or pause with a double click of the sleep/wake button. It also added the ability to turn the device off by holding the sleep/wake button. The user interface has also been enhanced. On October 4, 2011, the iPod Nano 1.2 update was unveiled at the Apple "Let's Talk iPhone" event at the Town Hall, 4 Infinite Loop. This update added the option to increase or decrease the size of the home buttons for easier use. The update also added a better fitness app, which has a better pedometer split into walking and running style. The update also included sixteen new clock faces, which include designs like a Nixie tube clock face or a old style clock face, or even Disney designs, like Mickey Mouse, or Kermit the Frog, bringing to a total of 18 clock faces. Three more background images were also added.^[45]
