- Originally, iPods were only MP3 players. As Apple released new versions, iPod screens got bigger and clearer. The technological advancement is seen in the 3.5-inch screen of the iPod Touch, which is big enough for watching videos -- in Quick Time or MP4 formats -- while on the go. Like all content, you have to load your videos and music files onto the Touch using iTunes, which is free.
- The iPod Touch also has two built-in cameras for communicating on the go. The primary camera is on the back of the device, and you can use it to shoot videos in 720p high-definition resolution or to take still photos. The second camera is in the front and is mostly used for Apple's Face Time, a video chat program that connects your iPod Touch with another Face Time-ready device over the Internet.
- So long as you are within range of a wireless Internet connection, the iPod Touch can be your Web browser. The Touch comes preloaded with Apple's Safari browser, and you can surf the Internet using Safari and the Wi-Fi functionality of the device.
- The Wi-Fi in the iPod Touch comes in handy for reasons other than surfing the Internet, too. Using your home network, you can link the Touch to your computer (or computers) to share the iTunes library. This means that you can sit in your bed upstairs and stream music and videos directly to your iPod Touch without plugging it in or without loading those specific files on the device; it's all done wirelessly.
- Just like the iPhone, the iPod Touch uses applications -- or apps. You download apps from the Internet to your device directly. These tiny programs range from HD games to simple calendars programs. Some Apps are free (or free to try) while others come with a ticket price.
