Is 16GB enough for a Nexus owner? I preordered the Nexus 5X w/ 16 GB thinking keeping costs down is important. I want to have the following in my android device: reliable software support, a good camera, fingerprint scanner, Android Pay support/NFC, a good processor, and a good form factor. What ways can I avoid having to pay $53.50 for more memory and then more for faster shipping?
