I'm planning to purchase the iPhone 4S sometime soon. I was leaning toward the 16gb model for budget purposes, however a recent review from a very legitimate source stated the 4S operating system is a resource hog, taking up a good 7 gigs of space, so to absolutely go with at least the 32gb model. I wasn't planning to do this. This will be my first iPhone, coming over from a Blackberry, so I wanted to get some opinions from knowledgeable Apple afficianados if the 16gb capacity would suffice. I don't really plan to keep a lot of music or videos on the phone - mainly using it as a phone, surfing the web, for some game and information apps and storing some photos. Looking forward to hearing your thoughts. Thanks!
