There are a lot of really great changes. The curved design feels fantastic, the screen size upgrades are great, the cameras have some awesome feature like slo-mo and OIS on plus, pretty great battery life, and Apple Pay sounds promising. What phone did you upgrade from? What phone did you get? Most importantly, what's your favorite new feature? I upgraded from the 5 to the 6 plus. I was a little intimidated by the size (ahem...that's what she said), but I am absolutely loving it. Honestly my favorite feature is the expanded landscape interface and ability. Being able to see home icons and navigate menus in landscape mode makes the 6 plus feels like a new experience. I hope Apple and devs expand upon this functionality. Your turn!
