there's only 2 things that is a major difference apart from customization and accessing settings
1. you can't easily transfer files to / from your device
2. it shouldn't be like that but i have found that the Android apps are more usable, easier to do work between a few apps, etc. (not sure why, in theory it should both be as functional)
Having said that, both are very good. wife lives on ios, i live on android, we agree to disagree
