I am about to get my first iPhone, and I need more information so I can decided whether to get the 16, 32, or 64 Gb. I have had an 8 Gig Palm Pre and still have plenty of room. But I will be taking more videos on the iPhone, and they are higher resolution. I won't need to store all of them on the phone for long as I'll be doing most of my movie editing on my Macbook Pro. What would I likely need the larger size for that I am not thinking of? Thanks.
