> Not having to worry about dongles, i.e. connecting USB devices to your machine

The dongles. OMG. It's worse than the parallel printer age. I cannot recall another period in history where I needed a dongle so often. USB-C only on Macbooks was such a huge design mistake. Especially in the era of USB-A! Soooooo many things are still USB-A. All for a little more thinness! It's really grating.
