The price difference is big, i wonder if its really worth it. I am a guy that backs up frequently, so i believe im gonna have a good control over the storage data. Real question is, when shooting video, doest it take up a lot of space and how easy is it to relieve the phone from data? Is it like Android, that you plug in a cable and see it as an external drive, so all the stuff you transfer, is like data from another drive? How much free space is available when one purchases the iPhone?
