Wait until you have to do tech support for someone who has a USB-C charging cable that doesn't work connecting their hard drive. Singular cable wasn't in the specs.
I’ll take that hypothetical problem over what we had in the past. A dozen different plugs, a dozen different cables, multiple required docks, incompatible charging bricks, proprietary plugs, and more.
I have yet to come across an issue with USB-C either personally or externally. But maybe some day it will happen. And I still won’t care because it’s better than it used to be.
