It’s going just fine, from my perspective. Unfortunately I now have three different types of cables (micro-B, USB-C and lightning), and it makes it extra challenging that USB-C is sometimes double ended, sometimes B-to-C. On the other hand, it’s very nice I can charge my new Framework laptop and iPad using the same cable cable and charger.

But it’s going quite quickly, and most of the apple devices I bought recently already have USB-C in one way or another, and the actual problem for me is replacing power banks and chargers so that they support USB-C as well. Most of them assume USB-C == “high power slot”, when I just need a few of them for smaller stuff (AirPods and Apple Watch both came with USB-C cables).

Happened a while ago, you have to go out of your way to find (new) android phones with Micro-B.
