iPod Scratch Protection
There's been a lot of chatter about the new iPod Nano scratching easily. However, it's made out of the same exact material as the full-size iPod. And while you do hear about scratching, it's nothing like the iPod Nano complaints. I think it is just so portable and convenient that it gets tossed around quite a bit in your pocket, purse, etc.
You could get an case for it of course, but it kind of takes away from the sleekness, thiness and sexiness of it.
An alternative is a "film" or "shield" where a thin coating of clear plastic coats the iPod. Macworld has a great article on this type of scratch protection.
If you do happen to have some scratches on your iPod, you can use good ol' fashioned inexpensive Brasso metal cleaner. It's mild abrasion buffs out scratches. I've done this on 3 iPods and the results are amazing. No need to spend a ton of money on special formulas.
