I've never understood why more people don't buy the 64gb. It seems like it should be either the 16gb or the 64gb. Going from 16-32 only increases capacity by 16gb but going from 32-64 increases it by 32 for the same price. Just seems like if you are gonna go 32gb you might as well go 64.
None of your post is rational. Perhaps this logic fits your personal situation, but many people, like myself, need more than 16 but not more than 32. Why would I drop the extra $100 on storage I don't need? Especially when I upgrade every year.
