One thing that makes the iPod Touch stand out from the other iPods on the market is that you can download a variety of apps from iTunes and the Apple App Store. There are texting apps, games, eBook readers and a large variety of other types of apps that will help you get things done or have lots of fun depending on what types of apps you are looking for. Or, you can choose a complete variety of apps for work and play.
If you look for apps straight from your iPod Touch, they will automatically upload to your device when you click on the download button for the app you want. If you are on your computer, the app will download to iTunes and then you can sync it to your iPod Touch the same way you sync music and other content from your iTunes library.
