When you’re designing a portable console, you need a huge battery, you need to keep it cool, and you need to be ready for the inevitable tumble. If you carry something around, you’re gonna drop it. The Nintendo Switch seems to hit all these points and more. The lion’s share of space is given to the batteries and the heat dissipation system. The fan is vibration-dampened to let it quietly run as much as needed.
