I'm a photographer, and currently have 15 gigs of photos on my macbook, 7 of which, came from my iphone. It's easy for me to put 50-100 photos a week on my phone, so I constantly transfer them to my computer and erase them from my iphone. It's gotten to the point where my phone slows down and I have no room to download apps or record voice memos until I clear some memory. But that was with the 16 gig. Hopefully it'll be better now that I ordered a 32 gig
