I got a 16GB 4 because the 16GB 3G was enough for me.
I ended up regretting that, because among other things, I didn't plan on taking more pics/vids with a better camera. It wasn't a ton, but it was enough to make 16GB tight, plus I just keep a lot of apps on the phone, so I should have gotten a 32GB. I really think 32GB is the sweet spot for all devices, unless you're planning on a lot of music or videos.
So this time, I got a 64GB, just to make sure I wouldn't regret not having more room.
I'm hoping this phone lasts me 3 years this time.
