As predicted, Apple announced the 4th generation iPod today.

Apple today introduced the new iPod, the fourth generation of the world’s number one portable digital music player, featuring Apple’s patent pending Click Wheel, which combines the smooth and continuous scrolling of a touch-sensitive wheel with five push buttons for superior one handed navigation. The new iPod also features up to 12 hours battery life and Shuffle Songs, a new command in the main menu which gives users instant access to one of the most exciting new ways to listen to their music library. All iPods work effortlessly with Apple’s iTunes®, providing music fans with the best digital jukebox on either a Mac® or Windows computer and access to the iTunes Music Store, the number one digital music service in the world. The new iPod is available immediately in a 20GB model for $299 and a 40GB model for $399.
