I'm looking to purchase a new video iPod and am looking for any suggestions being that I'm indecisive about which one to get. I like the looks of both the white and the black, but I'm wondering if the black is going to show more scratches and defects after time. I'm also trying to decide if the 30GB is going to be big enough, or if I should shell out the extra $100 to double the size. I realize these are brand new, and very few people have actually seen one in person, but any advice would be appreciated. Thanks!
