I'm thinking about getting an iPod classic for my birthday this year, and I had a couple of questions about it: - Is there any difference in the feel of the black and the silver versions? Do either of them scratch or scuff more easily than the other? - Is there any limit on the size of individual songs? I'm ripping my music right now in Apple Lossless format, and I want to play it on my iPod, but a couple of my songs are around 25 minutes long and would take up at least 100MB. - What is the display really like? Is it easy to watch videos and movies for any long amount of time?
