The iPod touch goes beyond that, including two cameras, wireless networking, built-in applications for e-mail and Web browsing and the option to install many of the thousands of applications available through the App Store. The iPod touch display screen covers most of the front surface of the iPod touch, making it resemble an iPhone. It also uses the same multi-touch interface that the iPhone uses instead of the click-wheel design on some other iPods.
You wake up the iPod touch with a simple press of its home button, and then navigate through music, videos and other files using your fingers and the touch-sensitive screen. The iPod touch might sound like the perfect blend of features from the original iPod and the iPhone; however, the iPod touch isn't for everyone. In this article, we'll look at how the iPod touch measures up to the iPhone and other iPod models.
We'll also examine the technology behind the multi-touch interface and the media player's technical specifications. It's easy to think of the iPod touch as a stripped-down version of the iPhone instead of a souped-up iPod. The iPod touch and iPhone look similar, featuring the same wide touch screen with a sleek black border and single home button. The iPod touch is a little smaller and weighs a little less than the iPhone, partly because the iPhone has a cellular transceiver.
The iPod touch's home screen also looks like the iPhone's, but with fewer icons -- at least, until you start installing new applications. From the home screen, you can get to the iPhone's text-messaging capabilities and collection of mini-applications called widgets.
And, of course, you can also use the iPhone as a cellular phone. The iPod touch doesn't share any of these features, but the two devices do have a few things in common, including:. The iPod touch also costs roughly the same amount as an iPhone or an iPod classic, but each of these devices has significantly different features and capabilities. Here's a run-down of the costs:. In terms of storage space, the iPod touch is comparable to the iPhone and the iPod nano, although it also comes in a 64 GB model.
The iPod touch also has far less storage space than the iPod classic, but their prices fall into a similar range. So when you buy an iPod touch, you won't necessarily get more storage room than on other iPod models. Instead, you'll get WiFi capabilities plus the large touch-sensitive screen and application interface of the iPhone. The thing that sets the iPod touch apart from other iPod models -- other than the latest nano -- is its touch-screen interface.
When you touch the screen, the iPod's circuitry detects the presence of your finger. It keeps track of how many fingers you have on the screen and where you move them.
It also gives the iPod touch the capability of running apps -- something even the newest iPod nano can't do. The iPod touch does this using a layer of capacitive material under a protective covering. You can read How Capacitors Work to learn more about them, but the basic idea involves taking advantage of the electrical properties of the human body.
When you touch a capacitive surface, the amount of charge it holds changes. This is why devices like the iPod touch require you to touch them with your bare skin -- insulating materials like gloves, pens and styluses don't cause the same changes in the capacitive circuitry. Regardless of which method the screen uses, you change the electrical properties of the screen every time you touch it.
The iPod records this change as data, and it uses mathematical algorithms to translate the data into an understanding of where your fingers are. In the next section, we'll explore what the iPod touch does with this data and how to navigate through its features. The program is free, although users have the option to browse the iTunes Store for cheap downloads. Usually, an iPod can easily sync up with iTunes with the help of a computer and transfer the music from the iTunes site directly to the iPod via a USB cable.
Users can easily sync their iPod with their home computer or computing device and send these files from one device to another. Depending on the type of iPod, users can transfer music files and view music videos, TV shows, full length motion pictures, and even digital photos. The iTrip, invented by Griffin Technology and released in March of , is a device that can be plugged directly into an iPod via the headphone socket and converts the audio output of the iPod into a constant FM radio signal that can be picked up by any radio within 15 feet.
One of the reasons why the iPod is so popular is its sleek and simple design. The device is very easy to use. Today, there are many different types of iPods available. These different types of iPods usually use one of two types of storage — miniature hard drives or flash memory.
Miniature hard drives can be smaller than 2 inches and fit as much as 80 gigabytes of data, making it extremely easy to store an entire music collection and download several full length motion pictures. On smaller sized units such as the iPod Nano and iPod Shuffle, a different type of storage media called flash memory is used. This type of storage unit usually holds from 1 to 8 GB of data.
The advantage of using flash memory is that it is even smaller than miniature hard drives and extremely thin, allowing an even smaller device to be created. The battery included in most standard iPods is a mah 3. The battery usually lasts between to recharge cycles, which, for some users, can last less than a year before the battery needs to be replaced.
The battery is created this way probably due to the form factor. The only inconvenience is that the user cannot open up the iPod and remove the battery when the battery fails, and it has to be sent back to Apple to be changed. The Click Wheel is perhaps the most convenient iPod feature. The hardware and software features of both devices are fairly similar though the iPod touch isn't updated as often as the iPhone, so the closest relative to the latest iPod touch is the slightly old iPhone 6 series.
If you've got an iPod touch, or are thinking about getting one, below is an overview of everything you need to know about the device, from understanding its hardware and software, answering some questions about buying it, and how to get help for problems.
Apple had sold well over million iPod touches. If you're considering joining the fun with your first iPod touch or by upgrading to a new model, you may want to consider which accessories you should buy, how to find a cheap iPod touch , and if you should buy an extended warranty.
Once you've gotten your new iPod touch, you'll need to set it up. The setup process is pretty easy and quick, and once you've completed it, you can get the good stuff, like:.

While the early models of the iPod touch all featured roughly the same set of hardware features, the options on the 6th generation listed below are modern and powerful, making the device a near alternative to the iPhone.
While the iPod touch is a great device, it's not completely trouble free and hey, what is? In your early days of using it, you may run into situations where it freezes. If so, you should be familiar with how to restart it.
When you're using the touch, there are a number of precautions you should take the protect yourself and your device, including:. Squeeze more juice out of it with tips to improve its battery life.
