With the Apple iPod touch, Apple has married the iPhone's revolutionary multi-touch interface to their popular digital media player. So instead of a Click Wheel, you just use your fingers to flick through your music, photos, and video. Two fingers can be used in a pinching or spreading motion as well, which zooms in and out of photos and web pages. That's right, the iPod touch is the first iPod to offer web access. It does this via built-in Wi-Fi support. There's even a special iTunes Wi-Fi Store, so you can browse and purchase new music and video while you're on the road.
