www.maclear.biz There is an Ultra clear zip pouch there that i ordered and it's great. It'll keep my ipod save until a better case is available The touch sensitive controls still work through the plastic.
That's nice, but this is (by far) the best 4g iPod case I've seen: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=56170&item=5714169581&rd=1&ssPageName=WDVW .narco
Haha. Actually, you'd be surprised how many people DO keep their iPods in socks. Albeit, not "custom" designed sock cases like that beaut.
I used to keep it in a sock as well. I have yet to find a case that doesn't scratch my iPod -- well, except maybe for these: http://foofbag.com/ .narco
