TheTechLounge posted a review on Apple's iPod nano

The Nano is currently Apple’s mid-priced iPod solution, falling between the iPod shuffle on the low end, and the new iPod video on the high end. The Nano integrates a color screen and the patented iPod control interface into a much smaller design than its bigger brother. Of course, you sacrifice the vastly superior storage capacity found in the full size iPod, going from either 30 or 60GB down to 1, 2, or 4GB of storage for the Nano. The Nano is for those of us that prefer a smaller, more convenient device and don’t require video playback or massive amounts of storage space.
