I realized I could delete pictures/video, etc. Is this an efficient way of managing memory? I was so set on the 64gb but then this thought came to mind. How effective do you think this would be? I've read many places the 16Gb just isn't sufficient anymore and I agree, with 7GB left, 10 apps, and no pics/video. Even though I can delete stuff on the 16, is a 64 still the better choice?
