As shown in Figure 4, the iPod Touch comes with a crisp and clear 3.5" multi-touch display at a resolution of 480x320 pixels. Like the iPhone, you simply put your finger on the arrow and slide your finger across the gadget to unlock the device.

Like the iPhone, the iPod touch has only a few buttons and ports. The side of the iPod touch, shown in Figure 5, has only an up/down volume rocker. In this figure you can also see the slender chrome-finish casing, which is typical of Apple’s great design.

In Figure 7, you can see the back of the iPod touch is shiny silver. There is a speaker port on the left near the top. The sound quality of this iPod touch is as good as any other iPod and the speaker, although not great, is loud enough to be useable for games, alarms, and the like.
Figure 7 also shows the slightly raised sleep/wake button on the top of the iPod touch.

Although Apple is pretty close-mouthed about the type of processors that it puts in its devices, we can tell you that the 8 GB 3rd generation model has a similar response time to the 2nd generation touch while the 32 and 64 GB 3rd generation models have a much faster response time and better graphic rendering.
