this has been discussed for years. I remember they said this about 10 years ago. you are not going to MAKE Apple give up their proprietary designs.
for what its worth, I do use the lightning connector a lot in the car still, although convenient, its not a necessity anymore because in the house I only use wireless charging and for my headphones I prefer lightning but can use BT. and I agree with
@R.E.N. Spells Ren that durability should be the main concern. I dont have a problem with Apple keeping their design, when you start letting it go universal, everyone will be making it then using with wrong voltage, etc, fukkin phones up and shyt.
