Before my present iPad mini, which is the 16GB version with 3G, I thought that I needed more space. I had a 32GB version. Then I was 'given' the one I have from work. I spent a few hours working out what I needed on there, and what was only on my old iPad because I had the space. I only filled 12GB, and I really haven't missed my old one with more storage. The only issue I've had was when I was upgrading to iOS 8.0 I had to do it over my mac, as the mini didn't have enough space.
