Folding power pins.
Folding power pins please, so they don’t catch in carryon luggage.
I second this; being able to flip down the power plug to make this a compact package with nothing to snag in luggage or laptop bag is really important for the next hardware rev. Right now, I am always worrying about the plug either snagging on something or the pins getting bent...
Ideally, I'd love a slide-in adapter similar to on Apple's power bricks with collapsing pins and an ability to swap out for international plugs (sold separately); however, I recognize that may take up too much internal space.
