Offering a slicker, cooler designed case, improved battery life and click-wheel navigation, the new fourth-generation iPod by Apple is almost upon us. "According to Newsweek magazine, the two new models will offer greater capacity for the same price as the current lineup. A 20GB iPod will sell for $299, while the top-of-the-line 40GB model will retail for $399. Currently, Apple sells a 15GB version for $299, a 20GB version for $399 and a 40GB model for $499." No word as yet on the availability date but one can only assume that its soon.
