I'm pretty much the opposite. I only have a 16 GB version and it's fine. I play a game, I finish it, I delete it. I don't keep a massive backlog, I play what I buy. It's a good way of keeping your spending down and appreciating the games you have properly. I fear I would just loose games in the cavern of my drive otherwise. I don't do music or videos (streaming!).
Same here. That's why 16Gb is enough for me.
