I'm one of the people who debated 64gb vs 128gb for awhile. I ended up grabbing the 64gb. After the OS and my 32gb of music I've got 20gb left. I've yet to take any pictures, add any movies or take video, or download any apps and whatever else. I know 20gb free is a lot, but really how much is it? Considering over at least the next two years I'll be using this phone to take videos, pics etc. I don't consider myself a power user, but maybe above average. I just want to make sure I get my money's worth in the long rung. So, roughly how many videos/pics etc. are we talking about that I'll be able to store on this thing with my 20gb free after music? Thanks!
