Just got a new MBA 13", and will be leaving soon for a round the world trip. I don't have a lot of money to spend on a Gelaskin, nor do I want anything that makes the laptop look fancy or expensive (security reasons). I'd like to protect it from scratches so I can sell it when I get back. Any thoughts to just putting some clean white duct tape over the whole thing? I know it'll look horrid, but thats half the point. thoughts?
