Earlier quoted context omitted.
I owned iPhone 8+ for a week and didn't notice any differences than iPhone 6 with jack for the sound quality. Only one bad thing, you can't be charging while listening to music.
I am considering switching from an iPhone 6 to an 8 Plus. Do you regret going for a bigger iPhone or not? I tried the 8 Plus in a store and it was much faster! But also much heavier, that's why I haven't made the jump yet.
Or I'd wait for the x, which has a bigger screen than plus but same size body as 8 (?).
