I like the fact that we're aligning on one connector but it's hard for me to praise USB-C in and of itself. The connector feels flimsy and has some slop/play in a way that lightning did not, and especially on lower-end devices.

The charging standards, voltages, and data rates, are frustrating because they're almost never labeled. This is especially true on low end, cables, and device devices. The worst offenders will only charge with a USB-A to C cable with low voltage, which is not what I hope for when I see a USB-C port on a device.
