I really don't want to have to buy more gb than I need.
I never download movies, I have about 100 songs max, I use instagram, twitter, snapchat, and a few other apps but that's about it. I do take photos but only a few, like max 200-300. I rarely video. I have a data plan that means I have unlimited internet so Im not worried about that. Will 8gb be okay for me for an iPhone 5c? People telling me its nowhere near enough, but I don't have games or anything, there really isn't a good enough reason for me to get 16gb.
HELP?

Why the issue, the cost between 8 and 32,so cheap, I would always get the more. I do not use mine that much, but 8 would never be enough for me.

In my opinion, I would go with the high capacity iPhone. It might not seem like you'll use a lot of space, but you will and it is better to have too much than too little. Considering the last few Major iOS updates require about 3-4gb of space, you'll need more than half your phone clear if you get the 8gb option.

No, 8GB is not enough. 16 GB is better.
