First of all, I'm euphoric because I am an Apple guy living in a Sprint family, waiting against hope that there would finally be a Sprint iPhone. Now at long last, I can be an entirely Apple guy. My question has to do with size. In the past, I have been a person who always opts for the largest, hence a 64GB iPad2, but as I reflect on reality with my iPad, I still have 40+ GB of space left, so I am curious what others think about 16 vs. 32 vs. 64. I preorder tomorrow, so I would greatly value your thoughts. As a retired teacher, I need to balance frugality with necessity.
