Next up we have the Developers who are continually improving and adding data to their titles.
Even if you plan today for an S4 16GB (remaining space on first boot = 9.62GB SIM Free or 8.12GB O2) there is no way you can be certain you will be able to run these same Apps in say 6 to 9 months time.
As an example SkySafari Pro has grown with it's associated data files from 760 to 925MB in the past few months.
Real Racing 3 has recently seen an update that has required more files added for extra races and cars.
In other words you can not plan accurately, it's all guess work.
In this case though, Samsung did plan ahead and offer 32 and 64gb models. It is the carriers who choose to stock them or not. The larger sizes are offered per Samsung for the Octa and Qualcomm chipsets.
Verizon as example could easily set the large sizes up for online orders only and allow the CUSTOMERS that actually PAY them money to decide. Kind of like thinking ahead for themselves.
