iPod touch has many built-in technologies that help it to support and play a lot of games with many graphics details.
One of the built-in technologies is the accelerometer, this technology is able to detect when your iPod is rotated from landscape to portrait or the other way, and then the iPod touch automatically changes everything you see on the LCD display. This technology comes into play when you want for example to see a photo from portrait to landscape or you play games. In the car games you will see that your iPod touch will become a steering wheel and if you play other games, for example Topple which is a balance game the accelerometer will help you play the game better.
The Multi-Touch interface allows iPod touch users, not just play games but interact with a game. This technology allows your iPod touch to be transformed into a musical instrument, for example a guitar or a drum and you can test your reflexes by tapping through the sounds of a track.
Bluetooth and WiFi technology allows you to play games with your friends on your iPod's. The WiFi wireless technology means that users can connect to the Internet anywhere they can find WiFi connections. This technology allows you to search the web, send an e-mail, download music or play online games. The Bluetooth wireless technology allows users to have a peer to peer game.
