The promise of USB-C is huge: standard plug for everything including charging, devices sharing power with each other, all the things over a single port. But wow, it is buggy compared to the old USB days. Like sometimes, devices just decide not to charge from a given USB-C connection. Hopefully this can still be improved, and USB-C doesn't turn out like #Bluetooth, where almost everyone feels like it regularly pranks them. I guess that's why there are still so many devices with headphone jacks
