2 ways. 1: the most obvious, it's one less cord you have to carry with you.

2: USB-C offers higher transfer speeds vs lightning. If you transfer a lot between your device and mac, you will notice the difference immediately. But that's playing devil's advocate, USB-C is an inferior engineering design, so, this is still going backwards, for Apple.

USB-C, ugh. 🤦From an engineering standpoint, the lightning cable is far superior ( the male end is on the cord, not the device).

I think it's cute, that people think apple is doing this because of anything the EU passed. 😂
