Description

The iPod Touch has the iPhone's multi-touch interface, with a physical home button off the touch screen. The home screen has a list of buttons for the available applications. The iPod Touch is equipped with Wi-Fi 802.11b/g. All iPod Touch models have included the applications Music, Videos, and Photos (collectively duplicating the standard functions of the iPod Classic), iTunes (providing access to the Wi-Fi Music Store), Safari, YouTube, Calendar, Contacts, Clock, Calculator, and Settings. Later models added Mail (accessing POP/IMAP/SMTP e-mail), Maps, Stocks, Notes, and Weather, which could also be added to the earlier models with the purchase of a US$20 software upgrade. Direct links to web sites can be added to the home screen by the user (called "Web Clips").

On July 11, 2008 the iPhone 2.0 Software Update was released for the iPod Touch for US$9.95. The update allowed first generation iPod Touch devices to access the App Store, download third-party applications, in addition to a host of minor "fixes". The iPod Touch 2.0 Software Update supports WPA2 Enterprise with 802.1X authentication.

Requirements

As supplied new, the iPod Touch needs a connection to a computer for initial configuration. Officially, Apple requires iTunes to be installed on either a Mac OS X or Windows operating system based computer for configuring the iPod Touch. On either operating system, the iPod Touch must be connected through a USB port.The first time the iPod Touch is turned on, a "connect cable to iTunes" graphic will be displayed continuously until the iPod Touch is connected to a computer running iTunes.

To use the iPod Touch for buying products at the iTunes Wi-Fi Music Store via Wi-Fi, an iTunes Store account must be created in iTunes and the account details then entered into the iPod.

Apple states that the following is required for the iPod Touch:
A computer running either:
Mac OS X 10.4.10 or later
Microsoft Windows XP with SP2 or later, or Vista (32 or 64-bit versions)
iTunes 8.0 (with the 2.1 iPhone OS update) or 7.6 for iPhone OS 2.0.x or earlier
Available USB 2.0 port

Ipod Shuffle 2nd Gen

All nine colors of the second-generation iPod Shuffle. The bottom row are the original colors; the top row are the "refreshed" colors (with the exception of the orange iPod). Silver units have been available throughout the life of the second-generation shuffle.

On September 12, 2006, Apple announced the release of the second generation iPod Shuffle, calling it "the most wearable iPod ever".[2] First shipments of the unit were slated for an October 2006 arrival, but actually started shipping on Friday, November 3, 2006.[3] The new generation featured a lone 1 GB model at US$79, GB£49, CA$89, AU$119 or €89 (France) in a silver brushed aluminum case similar to the second generation iPod Nano and the older iPod Mini. The new model is less than half the size of the first generation model at 41.2 x 27.3 x 10.5 mm (1.62 x 1.07 x 0.41 in), and is reminiscent of the iPod Radio Remote available for iPod Nanos and 5th generation iPods. Apple claimed it was the "world's smallest MP3 player". This size includes the new built-in belt clip; the actual unit itself is thinner, with the entire device weighing only 15.5 g (0.55 ounces). The power and shuffle/no shuffle switches were also separated into two controls to prevent accidental choice of shuffle when that may not be the desired mode of operation. The formatting of the iPod itself is new to Apple, as the 2G (2nd Generation) shuffle will only format itself to FAT32. iTunes issues a warning that the iPod is incorrectly formatted if brought to the Macintosh format HFS+. All previous iPod models have allowed the usage of either the Mac format or the Windows format.[4]

On the second generation iPod Shuffle, USB connectivity is provided via an included dock, which transfers data through the headphone jack. The second generation iPod Shuffle is also able to act as a flash drive, just like the first generation iPod Shuffle. However, unlike the first generation iPod Shuffle, the second generation does not have a built-in USB connector. This means the dock is required for connection to a computer on the second generation model.

The second generation shuffle can play MP3, MP3 VBR, AAC, Protected AAC, Audible (formats 2, 3 and 4), WAV and AIFF, meaning that the only iTunes format not supported is Apple Lossless. Using WAV or AIFF will very quickly fill the device's low 1 GB capacity. iPod Shuffle cannot play music from music video files.
 
On January 30, 2007, Apple announced the addition of four new colors to the iPod Shuffle line. In addition to the original silver, a pink, orange, green, and blue color has been made available via the Apple Store (online). Of the colors the blue, green, and pink are essentially the same hues as the second generation Minis and Nanos. The new orange color is a first for the iPod franchise. They also now come with the new redesigned headphones that were not included with the original silver model. The box was also changed to have gray text instead of the lime-green text, lime-green showing that the original headphones are included, and gray text showing that the new headphones are included.

On September 5, 2007, Apple refreshed the line with four new colors including a Product Red version. The new colors (turquoise, lavender, mint green, and Product Red) replaced the previous colors (pink, orange, green, and blue). On February 19, 2008, Apple reduced the price of the 1 GB model to $49 and announced the 2 GB version for $69 though the sale of the larger one was released later that month, The UK sale price is £32 for the 1GB version and £45 for the 2GB version.

Ipod Shuffle 1st Gen

According to Apple, owners of existing iPods had often left the music selection to "shuffle", and the new iPod Shuffle was a way of implementing that in a much more cost-effective fashion. It relies on the use of an "autofill" feature in iTunes, which can select songs at random from a user's music library (or from a specific playlist) and copy as many as will fit into iPod Shuffle's memory. It can hold up to 240 songs (1 GB model, based on Apple's estimate, of four minutes per song and 128 kbit/s AAC encoding). It used the SigmaTel STMP35xx System On a Chip, a flash memory IC, and USB rechargeable Lithium cell.

It lacks the trademark display, scroll wheel, playlist management features, games, address book, calendar, alarm, and notes capability of earlier iPods, and cannot be used with iSync. In addition, due to its lower processing power, it is incapable of playing Apple Lossless and AIFF audio files, unlike other iPod models. The iPod Shuffle has a better bass response than 4th generation iPod, according to one review published days after its release. The first generation shuffle weighed 0.78 ounces.

iTunes offers some new features for iPod Shuffle. One is the ability to reduce the bit rate of songs to 128 kbit/s AAC. The conversion is done automatically, with the original file left untouched on the computer and the smaller (lower bit rate) file sent to the iPod Shuffle. Older versions of iTunes allowed an iPod Shuffle playlist to be viewed and changed while the unit is not connected; the next time the unit is connected, it can then be updated with the changed playlist. This functionality is no longer a part of iTunes as of iTunes 7.

The front of the iPod Shuffle has buttons for Play/Pause, Next Song/Fast Forward, Previous Song/Fast Reverse, and up and down volume adjustment. On the reverse, it has a battery level indicator light (activated by a button) and a three-position switch to turn the unit off or set it to play music in order or shuffled. It plugs directly into a computer's USB port (either 1.1 or 2.0), through which it also recharges its battery, which has an expected life of around 12 hours between charges. The USB plug is hidden beneath a cap. The unit also comes with a lanyard that attaches to the iPod Shuffle via an attached cap and this allows the user to wear the iPod Shuffle around his or her neck.

The iPod Shuffle can also be used as a USB flash drive. iTunes allows a user to set how much of the drive will be allowed for storing files, and how much will be used for storing music.

First generation iPod Shuffles were originally sold at US$99 for 512 MB (0.5 GB) models, and US$149 for 1 GB models. In June 2005, the price for the first generation 1 GB iPod Shuffle was lowered to US$129. In February 2006, the prices for first generation iPod Shuffles were lowered to US$69 and US$99 respectively
