I would hate to have that much personal data attached to my phone. At some point, as it has in the past, I am going to lose my phone. I have my own personal cloud instead.
I have a 64GB card and between the selective images and music I choose to store on my phone, I still have plenty of space.
But, as the next gen of phones are 5G, I am more interested in speed for my phone and camera(s).
This looks promising as a trend...
