Hi Everyone, I am looking to get a refurbished 4th Gen. iPod from the Apple site. The 30GB Photo is exactly the same price as the 40GB monochrome model. I could really care less about the color screen (I would have no use for it), but as I understand, the battery life is better on the Photo models, which makes me lean towards that model a bit. However, I have a lot of music and 10 extra GB would be nice. Are there any other differences at all between the 4G Photo and monochrome models other than the color screen and improved battery life of the Photo? I am most concerned about sound quality, as well as whether the battery life difference is really noticeable or not. Thank you for any advice!
