Sometimes I wonder... Why did Apple make lightning connectors and thunderbird or bolt or whatever connectors..
Other days I know exactly why. I switched from Android from day 1 to an iPhone 7. I personally don't use the headphone so haven't noticed it. The battery is awesome. The UI reminds me of Windows 3.1. Far from perfect, hoping to switch back soon (battery life is killer for me, plus phone durability). Then I see more issues with Pixel or USB-C and it makes me want to be a luddite.
