Total Nightmare: USB-C and Thunderbolt 3
Personally, I am rather sad to see the Magsafe connector go, and having to sacrifice IO for charging while mobile seems like quite the headscratcher.It's somewhat funny that not only will you have to carry dongles for everything for a few years time, but also make sure you carry the right USB-C cables, as your friend's might not work. Yay we have superlight laptops, but need to carry a backpack full of spaghettied cables.
