I managed to pickup 2x 16gb 4S' that are due to arrive Friday for myself and my girlfriend. Thing is, I'm starting to question if I should just exchange mine for a 32gb model? I currently have a 16gb 3GS, and had a 16gb 3G before that, and in both cases I never used more than 8gb. However, with iOS getting larger the amount of available space keeps going down to 13gb now without anything installed on it. I'm guessing it'll take up a bit more on the 4S as well due to Siri. Thing is, I hardly ever use the camera or video on the 3GS bc it's so slow and takes such poor pics so that's never really been a consideration I've had to deal with. Plus, I have a 64gb iPad that I use for video on trips, but 99% of the time it sits with barely 6gb used. I really want to be able to get by with only 16gb (~13gb usable), but I'm really having 2nd thoughts. I know 64gb is both more than I'm willing to spend currently as well as overkill as I have seen with my iPad. Then again, I don't store any music on the iPad while I keep ~2gb of stuff I like on my 3GS currently. I understand that everyone's usage and tastes are different, but I am curious to see what others think. I've always had 16gb and it's been plenty. I'm just afraid that at 8mp photos and 1080p video (when/if I use them) will really add up. Mind you, I have no issues with having to dump photos/video off the device regularly as I try to keep things organized.
