When Apple released the iPod video in 2005, people started wondering what the next version of the iPod would look like. It seemed obvious that the media player needed a bigger screen. While a 2.5-inch LCD was fine for browsing through lists of artists and songs, it was far too small for watching videos, especially in a widescreen format.

Apple released the first version of its iPod touch in 2007. Since its release, the iPod touch has become a popular portable media player. Its sibling iPod models specialize in audio and video playback, which is great if that's all you need. 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.
