IPod nano

The iPod Nano is a portable media player designed and marketed by Apple. It is the mid-range model in the iPod family. It uses flash memory, like the iPod shuffle, but with a 2-inch (diagonal) QVGA display and the "click wheel" found on the iPod Classic. The model has been updated six times since its introduction. Shortly after release, the iPod Nano became the highest-selling MP3 player in history, being more successful than its discontinued sibling, the iPod Mini.

Features
Instead of the hard disk which is used in the iPod Classic, the Nano uses flash memory. This means there are no moving parts, making the iPod Nano resistant to hard disk failure due to sudden movement.

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, such as Linux). It connects to the computer via the same proprietary dock connector as all models since the iPod 3rd Generation (with the exception of the iPod Shuffle), using USB 2.0. The current iPod Nano does not support syncing over FireWire, but the first three generations can be charged via FireWire. 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 as well as the volume limit function.

Like previous iPod models, the first and second generation iPod Nano include some pre-installed games: Brick, Music Quiz, Parachute, and Solitaire. The third generation iPod Nano includes pre-installed games, but can also run games which Apple makes available for purchase in the iTunes Store. The three pre-installed games are variations on the Brick, Solitaire, and Music Quiz games found in the first and second-generation iPod Nanos. Brick is now called Vortex and there is now a circular playing field. Solitaire is now called Klondike with minimal differences. Music Quiz now includes Movie and TV Show trivia along with a more aesthetically pleasing look. The fourth generation also includes Maze, which uses that model's accelerometer to move a ball around to try and collect glowing orbs by tilting the ipod.

Unlike the preceding iPod Mini, its battery is soldered to the printed circuit board of the device, making it harder to replace manually, although replacement batteries are readily available.[citation needed] The flash memory chips used are surface mount devices, making any attempt to upgrade the Nano's storage capacity impractical.

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; newer versions using the dock connector have been made. The first generation iPod Nano did not support voice recording; the second and third generation Nanos function with third-party recording attachments. It did not function with either Apple's iPod Camera Connector or other camera connectors from third-party manufacturers.

iPod Nano 1st Generation
Originally called the iPod Mini, Apple introduced the iPod Nano at a media event on September 7, 2005. At the beginning of the event, Steve Jobs pointed at his watch pocket from his pants and asked the audience: "Ever wondered what this pocket was for?" describing the size of the iPod Nano. The screen on the original Nano was only 1.8 inches but the stated battery life lasted up to 14 hours.

iPod Nano 1G Battery Risk
In around November 2011 Apple.inc announced that the iPod Nano 1st Generation had a battery issue, where small and metallic particles were accidentally introduced in the battery, which might make it overheat or explode without overheating, this was announced due to the increment of accidents with the music player over the years. iPod Nano 1g users can actually report their unit and recieve a free replacement, users can recieve an iPod Nano 6g with 8gb in silver color.

iPod Nano Second Generation
The next iPod Nano was released on September 12, 2006 a year later than it's older brother. The new iPod Nano looked alot like the iPod Mini line. It was available in several different colors, (Silver, Green, Pink, Blue, and Black) but unlike the second generation iPod Mini and the first generation iPod Nano, the click wheel is gray on the iPod Nano second generation except for the black edition. Improvements are that the screen size is bigger, and the battery life grew from 14 hours, to 24 hours.

On October 13, 2006 Apple announced a new "Product Red" iPod Nano with 4GB of storage. Anyone who buys the red iPod Nano in the United States, Apple will donate $10. On November 3, 2006 Apple released the 8GB red iPod Nano due to popular demand.

Third Generation
Apple released the third generation of the iPod Nano on September 5, 2007. New improvements are a new 2 inch display, a new interface, and a shorter wider design. The pink model iPod was released on January 22, 2008.

Forth Generation
On September 9, 2008 at the Lets Rock Event, Apple released the fourth generation iPod Nano. It returned the design of the first and second generation iPod Nano slightly and was available in many different colors. Apple claimed that battery life for music playback would last 24 hours while video playback would only last 4 hours unlike the previous generation which lasted 5 hours. The iPod Nano also introduced an accelerometer so when you tilted it sideways you could search the cover flow, which had a totally different interface like the iPod Touch cover flow. Product Red was only available on Apple's website at the retail store.

Fifth Generation
On Apple's Lets Rock Event in 2009 a 5th generation iPod Nano was introduced. It looks the same as the fourth generation except the video camera is introduced which you can find on the bottom left corner in the shape of a microphone. The screen is also bigger and the device is thinner and more glossier. Unfortunately for users who bought the iPod Nano 5G, the battery life will only last an hour by the most so it is recommended to keep it charging at all times when being used. Another unfortunate fact is that the camera can only take video, not pictures. This iPod was described as the least best iPod in history.

Sixth Generation
The sixth generation iPod Nano features a complete new 1.5" design like the iPod Shuffle except with a 1.4.9" multi touch screen. The interface is also different and looks like a knocked down version of the popular iOS. The new iPod Nano removes video recording and music videos, and some even said that it removes voice recording, but it is revealed that when you plug in the mike accessory a voice memos app will appear. You can sync videos onto the iPod Nano and pictures, but it isn't very popular because of the tiny screen. Lastly, the iPod Nano 6th gen battery hasn't improved over the 5th gen and there is a small clip so you can listen to music while you are jogging or at the gym.

Seventh Generation
The seventh generation iPod nano was been announced on September 12, 2012. It features a 2.5 inch screen and multitouch gestures. It as a iPhone/iPod Nano 2g Hybrid shape, the icons are based in iOS icons, except that they are now circle shaped. It also features a new 8 pin connector called Lightning.

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

Apple's release of the iPod Nano as a replacement for the iPod Mini was viewed by many as a risky move. Steve Jobs 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 reported fine scratches on Nanos, caused by microfiber cloths. Other owners reported that their Nano's screen cracked without use of excessive force. On September 27, 2005, Apple confirmed that a small percentage ("less than 1/10 of 1 percent") of iPod Nanos shipped with a faulty screen and agreed to replace any that had cracked screens, but denied the iPod Nano was more susceptible to scratching than prior iPods. 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 claimed that the devices "scratch excessively during normal usage, rendering the screen on the Nanos unreadable, and violating state consumer protection statutes". Similar lawsuits were later filed in Mexico and the United Kingdom. In early 2009, Apple was in the process of settling a court case over the scratched iPod Nano screens. It was suggested that Apple should set aside $22 million to refund users. At the time, it required a Judge's sign-off on the terms by April 28, 2009. 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.

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

In another incident, a man's iPod Nano set his pants on fire while he was working at Hartsfield-Jackson Atlanta International Airport. Apple Inc., refused to release a statement regarding this issue.

In addition, an iPod Nano sparked in Japan in January while it was recharging. Although no one was injured during the incident, Apple Inc. investigated the incident. 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. On August 10, 2010, Apple Japan released a statement saying that it would replace any iPod Nanos that overheated.

Since 2010, users have been reporting the 6th generation iPod nano's sleep/wake button remains stuck after months of use, making it impossible to activate the device without the help of a computer or a dock accessory. According to a technical inspection, the device uses a double-sided tape to hold the button in place, indicating a possible design fault.

On November 11, 2011, Apple announced the iPod nano (1st generation) Replacement Program, intended to address concerns over overheating batteries. 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. During the replacement process, there have been several reports of users receiving an iPod nano 6th generation as replacement instead of the expected 1st generation device that users sent in during the recall. Because using the iPod nano 6th generation with a Mac computer requires iTunes 10 or higher, which in turn requires Mac OS X Leopard system software, Apple will upgrade the system software of participants running earlier versions of OS X, on request but this leaves users that do not have access to iTunes without a working device (because Apple changed the hashing of the music database which prevented the 6th generation iPod Nano from being used with open source software via libgpod. ).
