Sure the green Nanos inside Trade2Line Technology’s and N&X’s iPod crystal case may not be functional devices but they do give us a “real” idea what an actual Nano 4G looks like, in case the Nano diagrams fail to appeal to all your senses. Both mockups are green and exhibit the prominence of the long screen the new iPod is now sporting.

The final product, though, may have the edge smoothed a bit like this rendering from Elecunited Plastic, which has a silicon case ready for the Nano when it arrives. Their Nano is a lavender color and retains the curved screen of the original leakage from Kevin Rose.
