Please bring Apple Pay to more countries. My future iPhone 8 would be so awesome if I could also pay with it.
Yep, together with reliable maps with transits and walking/cycling integration; better Siri integration and a Siri which does more then timer settings; better iCloud offerings (unlimited photo uploads when buying a Mac, iPad or iPhone (google does that when buying a Pixel)); better file management between iCloud and iOS (more customizable); more customization of the icons on the screens (the look and feel is getting dated).
