I would still get the 256GB even if they offered 128. 87GB its too close to the 110 or whatever it is that you get on the 128GB and I don’t have any movies or TV shows on here at the moment.It made me wish Apple offered a 128gb option. 64 isn't enough but 256 is way too much and also stupidly expensive, which is why they do it.
I now have ALL video and pics of my kids, plus music and apps on my 512 Xs. I have about 160GB left. I love it!
ICloud storage for me is at 50GB...mainly for backups of my apple devices.
