i filled up my 16gb quickly. I have a decent amount of apps, but there isn't much room if you want to add music and lots of pics and vids. I would get the 32 if I could go back. Overall I love the phone. I haven't been bored since I got it. It is a god send at the DMV or docs office. The samsungs are cool, but I still think the iphone crushes anything else out there.
