Armor for Your Zune
"Since getting my Zune a few months ago, it has been in the very precarious position of having no screen protector, and only the supplied fabric slipcase to protect it from keys, pens and other devices. But when I use it to watch video, it has to go caseless. I was very happy to receive the Zune metal case and screen protector from PDAir, so that I could quit my worrying."
Gear Diary has a review up of a nice metal Zune case from PDair. The aluminum case adds some nice scratch protection, with very little additional bulk. This case doesn't offer any real protection for the screen; you'll need an additional screen protector, also reviewed by Gear Diary. Check out their full review for all the details!
