OK, against my better judgement I parted ways with my iPhone. I miss it and want it back, found a dude who has two of them (16GB Space Gray & 64GB Silver) at a decent price. I am a chronic switcher who will most likely end up with the next iPhone anyway so I really just need to get through them summer. I've never maxed out the memory on a 16GB device. That said, I'm looking ahead at potential resale values. Is it worth it to spend the extra $100 now to get more back in the long run?
