If it was 32, 64 and 128GB, I would have to think very hard about paying $100 to go from 32 to 64GB. $100 to go from 32 to 128GB would be a no brainer. I don't use the full 64GB on my phone now. 128GB would be nuts. I guess for sure I'd download my entire music collection. I'd still have 30+ GB free.
