I own a nTB 13' 2016 MacBook (bought the moment they were announced). One thing that I noticed a while ago is that the power cable that shipped with the computer is quite "loose" when plugged into any of the the USB C ports of the MBP. It doesn't seem to be form the ports themselves, since the "looseness" of the usb C power cable is the same on both ports, and other USB C devices plugged into the same ports holds up and "snap in" pretty well. (by comparison the power cable does a very subtle and loose "snap" when connecting). Clearly it seem to be the cable, BUT the thing that is weird is that the same cable is very very tight and snappy when connected directly into the power brick. (because you can reverse the cable and plus whatever end of the cable either on the computer or in the power brick). My thinking is that it's somehow intentional from Apple for the connection to act a bit like a "cheap magsafe", make the connector disconnect instead of bringing the laptop with it. However, I'm curious to see if other users of 2016 MBP noticed the same thing.
