I have a 16 GB 2G ipod touch. Currently using 2.0 GB of 16 GB. I plan to purchase the iPhone 3G S. I think 16 GB should be more than enough based on my ipod touch storage. I may take take some photos with the iPhone, & will take little or no videos. Even if I do take videos, I should be able to copy to PC for storage, correct? Is 16 GB storage capacity close to equivalent (overhead) on ipod touch & iPhone?
