iLounge couldn’t wait until Friday to receive its 40GB iPod, so we went to our local Apple Store and picked up a new 4G 20GB iPod for review. It’s being put through its paces as we speak. And yes, though the numbers show only a .12” difference, the new 40GB version feels surprisingly thicker (3G size, even) than the new 20GB. Retail Apple Stores have received “lots of them” in both sizes, and they’re already going quickly. Check back here for updates.
