Just curious how those who want a 128 GB iPhone would use the space based on their current and planned usage. For me personally, half of it would be used for ALAC music files. Then I'd keep many of my files on iCloud Drive, which, when cached on the device, would take up probably 510 GB. Then another 10 GB for photos, messages, and "Other". And lastly, about 10 GB for apps and games.
