If you are concerned about storage space somewhere along the line in the future, then I would definitely recommend upgrading to a model with a higher capacity; perhaps the 32GB model. When I got my 16GB iPhone 4, I didn't think I would come very close to using all up all of the available memory, but I'm pretty close. I have 2.7GB remaining with over 1,600 pictures (including videos) and almost 2GB of music. When it comes time for me to upgrade, I will definitely hold a 32GB model to a higher regard.
