Due to the specs of the camera and use in my job, I need mobile storage for high resolution pictures and videos so went with the 64GB. Even 'empty' of my stuff, it's still gobbling up nearly 15GB of that amount for just the phone and basic apps. That would be nearly half of the 32GB phone. I tend to buy and keep devices (had the last one for nearly a decade) so tend to buy with future needs in mind. Originally, I had looked at the Note4 because it had external storage options and an easily replaceable battery but decided on the Moto because of build quality and a slightly smaller footprint. For an additional 25% on contract, I felt the 64GB was a good investment.
