Well I think I just found the coolest 5th generation iPod nano case, The Kickster from Quirky. This brilliant design is a case, stand and cord tidier in one.
The Kickster design was crowed-sourced from the Quirky community over a 24 hour period. As soon as Apple announced the fifth generation iPod Nano the people at Quirky went to work on a case to keep all iPod fans happy. An interestign thing about Quirky, if you didn;t know, is that all the cool things on their ebsite are designed by the Quirky community – anyone can register free and get involved. If you want to influence a design – suggest modifications or improvements, brainstorm product names, etc, then you can earn yourself a percentage of the profits of that product. Pretty neat system.
Here are some awesome bigger shots:

And a detail shot of the iPod cord/headphone wrapping and tidying functionality:

So the Kickster incorporates the following features:
- A Hard plastic exterior.
- Full body and depressed screen protection so your screen can avoid surfaces and scratches.
- Integrated shock-absorbent silicone pad and cord wrap.
- Integrated swivel kickstand, which allows you to position your nano vertically or horizontally. Also functions as a hand-steadying grip for shooting video.
- Cut-outs for access to ports, buttons, microphone, and camera; you don’t need to remove it from the case to plug it in.
- Two-piece design clip for easy loading andunloading.
