I've noticed that when I have mine on my lap (I tend to sit cross-legged) it seems to put pressure on the USB-C cable/port. I never had any problems using a MacBook on my lap with the MagSafe power adapter because it would just fall off if the laptop leaned on it with too much pressure.

I think the USB-C port would be better in the back of the laptop instead of on the side where it gets in the way & becomes loose if you use it anywhere other than a flat surface.
