Hi, I've just recently purchased a 2nd generation silver iPod nano. I'm lovin it!!! I've purchased a silicon skin for it on ebay. However, after a few days of use I must say that I dislike camouflaging my new slick nano. Yes, I know, it does need to be protected if I want it to be in perfect condition.. But unlike the 1st g nanos or the 30/80gb iPod videos, are the 2nd g nanos scratchable? I usually tended to think that the 2nd g nano solved the "scratching" issue? Does one really need a case/skin for it if you want it to remain scratch free? Will my screen and case be scratched if I won't use a skin? Thanks!
