What are you planning for the extra space? I bumped my wife from an iPhone 4 16gb to a 5 with 32gb. Her 4 is mostly full with just pictures. I figure she'll be using the better camera even more, taking more videos, etc, and will use the extra space. I went from a 32gb 4 to a 64 gb 5. In part for the camera space, and so I can keep more music and videos on there. So what are you going to do with the extra space?
