Similar Hardware

• The iPhone and the iPod Touch use almost exactly the same hardware, across all three generations. An iPod Touch, from a hardware standpoint, is an iPhone with features removed.
  
  

No Camera on the iPod Touch

• While the iPhone has a camera built in, the iPod Touch does not. They run exactly the same operating system, "iPhone OS," making it less worthwhile to disable the camera-to-computer interface on the iPod Touch.
  
  

Disk Mode Is Gone

• Other types of iPods (Classic, Nano, Shuffle) all support some form of direct access to the storage media. The iPhone and the iPod Touch do not.
  
  

Uses of the Camera Interface

• On the iPhone, the camera-to-PC interface is used to transfer photos taken with the built-in camera. While the iPod touch has no camera, it does have the capability to save images downloaded from the Internet.
  
  

IPod Nano

• The Nano is a special case. While it has a camera, it will only use the camera-to-computer interface when disk mode is turned off. Otherwise, it acts exactly like a normal iPod, allowing full read-write access.
