I just got my iPod Photo today and I noticed something new in my iPhoto Library folder... There is a new folder called the iPod Photo Cache and it is taking up 2.63 GB of my hard drive space!! I guess this is what the hour-long process of "Optimizing Photos" was when I first pugged in my iPod. This seems kind of ridiculous to me. Does anybody who has an iPod Photo have a solution for this? I don't know if having my iPhoto Library on my iPod is worth wasting that much hard drive space!
